I am having this very confusing issue and I could only find someone who had the same issue 9 year ago but it wasn't solved : Posting a hidden field with whitespace removes content after whitespace.
First of all I'm very new to programming so pardon me if this is a very obvious issue and if my bug is very ugly !
Basically I am trying to pass the content of a variable through the value parameter of an input tag inside of a form. This variable contains strings separated by whitespaces ("test space space")
My goal is to then manipulate this data in a view through request.POST
The issue is that the first word gets passed just fine but anything after the first whitespace isn't passed to the database.
Note that I am using the same variable elsewhere in the same template and the entire title is displayed without issue
Here is my view :
#login_required
def watchlist(request):
user = request.user
all_watched_auctions = WatchedAuction.objects.all()
user_watched_auctions=all_watched_auctions.filter(user_id=user.id)
if request.method == "POST" :
auction_info = request.POST
user_id = auction_info.get('user_id')
auction_id = auction_info.get('auction_id')
title = request.POST.get('title')
# #creating a watched auction
auction_to_watch = WatchedAuction(user_id=user_id, auction_id=auction_id, is_watched=True, title=title)
# #preventing duplicates
if auction_id not in user_watched_auctions:
auction_to_watch.save()
test = user_watched_auctions.values_list("auction_id", flat=True)
active_listings = Listing.objects.filter(status="ACTIVE")
return render(request,"auctions/watchlist.html",{
"watchlist" : test,
"listings" : active_listings,
"user" : user,
})
And here is the template. You can skip to the end. That's where the troublesome form is :
{% extends "auctions/index.html" %}
{% block title %} {{listing.title}}{% endblock %}
{% block h2 %}
{% if listing.status == "ACTIVE" %}
<h2>Listing is active</h2>
{% else %}
<h2>Listing is inactive</h2>
{% endif %}
{% endblock %}
{% if messages %}
<ul class="messages">
{% for message in messages %}
<li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li>
{% endfor %}
</ul>
{% endif %}
<div>
<div>{% block test1 %}
{% if test.id == listing.id %}
{{block.super}}
</div>
<div>
</div>
{% if listing.author_id == user_id and listing.status == "ACTIVE" %}
</div>
<form action="" method="post">
{% csrf_token %}
<a href="">
<button> Close listing </button>
</a>
</form>
{% endif %}
{% if listing.author_id != user_id and listing.status == "ACTIVE" %}
<form action="{% url 'watchlist' %}" method="post" value="test.id">
{% csrf_token %}
<input type="hidden" name="user_id" value={{user_id}}>
<input type="hidden" name="auction_id" value={{listing.id}}>
<input type="hidden" name="is_valid" value=True>
<input type="hidden" name="title" value={{listing.title}}>
<button type="submit"> add to watchlist</button>
</form>
{% endif %}
{% endif %}
{% endblock %}
Thanks a lot to anyone taking the time to help me !
Most Probably this is due to lack of quotes between actual value value="actual_value". You can use single quotes or double quotes according to your html. Please try this way. It may work.
<input type="hidden" name="user_id" value="{{user_id}}">
<input type="hidden" name="auction_id" value="{{listing.id}}">
<input type="hidden" name="is_valid" value="True">
<input type="hidden" name="title" value="{{listing.title}}">
<button type="submit"> add to watchlist</button>

I am using the django all-auth login form. I wanted to customize the look of the form fields so I changed login.html within the account folder to look like this:
<form class="login" method="POST" action="{% url 'account_login' %}">
{% csrf_token %}
{% for field in form.visible_fields|slice:'2' %}
<div class="row form-group">
{% if field.name == 'login' %}
<input type="text" placeholder="Email"><i class="fas fa-at"></i>
{% else %}
<input type="password" placeholder="Password"><i class="la la-lock"></i>
{% endif %}
</div>
{% endfor %}
Forgot Password?
<button type="submit">Sign In</button>
</form>
The form renders exactly how I would like it to, however nothing happens when I click on submit. What is strange to me is that the form submits perfectly fine if in place of my for loop I simply type {{ form.as_p }}, it just doesn't look how I want. Can anyone see an error in my loop, or is there something else wrong here. I have been looking for a solution online but so far been unsuccessful
You need to specify the names of the fields in your input tags otherwise the POST dictionary will be empty. You are using {% if field.name == 'login' %} but you forgot to specify the name attribute. Same applies for the password input.
<form class="login" method="POST" action="{% url 'account_login' %}">
{% csrf_token %}
{% for field in form.visible_fields|slice:'2' %}
<div class="row form-group">
{% if field.name == 'login' %}
<input name='login' type="text" placeholder="Email"><i class="fas fa-at"></i>
{% else %}
<input name='password' type="password" placeholder="Password"><i class="la la-lock"></i>
{% endif %}
</div>
{% endfor %}
Forgot Password?
<button type="submit">Sign In</button>
</form>
I have a model form and I wanted to know if it is possible to take a model form and assign the name of the specific field when it is running through a for loop within the template html file.
Here is what i have in the current html template:
{% extends "base.html" %}
{% block content %}
<h1>Add members to {{record.name}}</h1>
{% if message %}
<p>{{message}}</p>
{% endif %}
<form action="." method="POST">
{% csrf_token %}
{% for trans in transactions %}
{% if trans.record.id == record.id %}
{{ trans.user.username }}
{{ form.as_p }}
{% endif %}
{% endfor %}
<p>Tax: <input type="text" name="tax" value=""></p>
<p>Tip: <input type="text" name="tip" value=""></p>
<input type="submit" name="submit" value="submit">
</form>
{% endblock %}
here is the current form model:
class IndividualSplitTransactionForm(forms.ModelForm):
class Meta:
model = Transaction
fields = ['amount', 'description']
currently the format is looking like this:
omar
amount
description
hani
amount
description
assad
amount
description
tax
tip
so when i process it and i want to grab the amount assigned to each of the specific users and update a record. I want it to look something like this for easier processing in the view.
omar
omaramount
omardescription
hani
haniamount
hanidescription
assad
assadamount
assaddescription
tax
tip
so that when i am processing I can properly assign the corrent amount and description for each user when i am updating existing records with the amount.
is it possible to do that within the template itself or would i have to do it somewhere else.
UPDATED
So i tried to change my code and update it to get what i am trying to get but this is what i am getting...
Here is the html
{% extends "base.html" %}
{% block content %}
<h1>Add members to {{record.name}}</h1>
{% if message %}
<p>{{message}}</p>
{% endif %}
<form action="." method="POST">
{% csrf_token %}
{% for trans in transactions %}
{% if trans.record.id == record.id %}
{% for field in form %}
<div class="fieldWrapper">
{{ field.errors }}
{{ trans.user.username }}{{ field.label }}{{ field|safe }}
</div>
{% endfor %}
{% endif %}
{% endfor %}
<p>Tax: <input type="text" name="tax" value=""></p>
<p>Tip: <input type="text" name="tip" value=""></p>
<input type="submit" name="submit" value="submit">
</form>
{% endblock %}
and here is what I am getting.
request returs
So if you look at the image, it is still just returning the last amount and description of the three that i entered... should i just create the whole form manually in the html file....
If you wanted the username + amount or username + description, then you to change away from form.as_p, because you will get the html <p><p/> tag for each field with label preceding it.
You want to dynamically add username then do by designing your own html content of the form manually.
There is a label_suffix, but prefix is not available. Even with suffix you should be doing it at the time of creating the form object.
Update:
{% for field in form %}
<div class="fieldWrapper">
{{ field.errors }}
{{ trans.user.username }} {{ field.label_tag }} {{ field }}
{% if field.help_text %}
<p class="help">{{ field.help_text|safe }}</p>
{% endif %}
</div>
{% endfor %}
My current template structure has a home.html that extends from a base.html. That home.html file also has its own {% include %} tags that pull in from other templates (contact forms, etc).
The problem I am having is that when I use the {% include %} tag on a class based view, nothing gets rendered in my template. I can still go to the url of the class based view and it renders just fine there.
In this case frontpabe/contact.html is a typical function based view, while frontpage/skills_list.html is a class based view.
home.html:
<div class="col-lg-4">
{% block contact %}
{% include 'frontpage/contact.html' %}
{% endblock %}
{% block skills %}
{% include 'frontpage/skills_list.html' %}
{% endblock %}
</div>
contact.html:
{% block contact %}
{% if errors %}
<ul>
{% for error in errors %}
<li>{{ error }}</li>
{% endfor %}
</ul>
{% endif %}
<form action="" method="post">
{% csrf_token %}
<input type="text" name="subject" placeholder="I want a free estimate...">
<p></p>
<input type="text" name="email" placeholder="email address (optional)">
<p></p>
<textarea name="message" placeholder="here are some things I need..."></textarea>
<br />
<input type="submit" value="Submit">
</form>
{% endblock %}
skills_list.html:
{% block skills %}
{% for item in skills_list %}
<h3 style='background-color:yellow;'> {{ item.skills }} </h3>
{% endfor %}
{% endblock %}
Your problem won't have anything to do with whether it's a function-based view or a class-based view--the {% include %} tag merely includes the template itself--it doesn't call the view. It's literally as if you just copied + pasted the text of the contact or skills templates into your front page template.
Without seeing the rest of your code, I can't be 100% sure, but a likely place for your problem is that the view class or function for your homepage doesn't have a variable skills_list or, if it does, that it is empty. So your skills_list.html template is being used, it's just rendering the results of looping over an empty list (a quick check would be to add a tiny bit of static text, like "HELLO?" to skills_list.html outside of your {% for ... %}; if you see that, you're definitely rendering the template.
If it is a missing skills_list variable, it's almost certainly because of the misunderstanding about views/templates. You're probably defining that template in the CBV associates with skills_list.html template--but, again, the {% include %} tag doesn't call your view; it just includes the raw template itself.
Extends and include are different and should not be used together. If you are going to define blocks then have the children template extend the parent and override the blocks- no includes necessary:
home.html:
<div class="col-lg-4">
{% block contact %}
{% endblock %}
{% block skills %}
{% endblock %}
</div>
contact.html:
{% extends 'home.html' %}
{% block contact %}
{% if errors %}
<ul>
{% for error in errors %}
<li>{{ error }}</li>
{% endfor %}
</ul>
{% endif %}
<form action="" method="post">
{% csrf_token %}
<input type="text" name="subject" placeholder="I want a free estimate...">
<p></p>
<input type="text" name="email" placeholder="email address (optional)">
<p></p>
<textarea name="message" placeholder="here are some things I need..."></textarea>
<br />
<input type="submit" value="Submit">
</form>
{% endblock %}
skills_list.html:
{% extends 'home.html' %}
{% block skills %}
{% for item in skills_list %}
<h3 style='background-color:yellow;'> {{ item.skills }} </h3>
{% endfor %}
{% endblock %}
Alternatively, you could use includes:
home.html:
<div class="col-lg-4">
{% include 'frontpage/contact.html' %}
{% include 'frontpage/skills_list.html' %}
</div>
contact.html:
{% if errors %}
<ul>
{% for error in errors %}
<li>{{ error }}</li>
{% endfor %}
</ul>
{% endif %}
<form action="" method="post">
{% csrf_token %}
<input type="text" name="subject" placeholder="I want a free estimate...">
<p></p>
<input type="text" name="email" placeholder="email address (optional)">
<p></p>
<textarea name="message" placeholder="here are some things I need..."></textarea>
<br />
<input type="submit" value="Submit">
</form>
skills_list.html:
{% for item in skills_list %}
<h3 style='background-color:yellow;'> {{ item.skills }} </h3>
{% endfor %}
I am trying to redirect the user back to the page where the comment was posted. I found this post on Django's site but I am doing something wrong because it won't redirect back.
Where should the input be placed to have it properly redirected?
{% load comments i18n %}
<form action="{% comment_form_target %}" method="post">{% csrf_token %}
{% if next %}<input type="hidden" name="next" value="{{ next }}" />{% endif %}
{% for field in form %}
{% if field.is_hidden %}
{{ field }}
{% else %}
{% if field.errors %}{{ field.errors }}{% endif %}
<input type="hidden" name="next" value="{% url proposal proposal.id %}" />
<p
{% if field.errors %} class="error"{% endif %}
{% ifequal field.name "honeypot" %} style="display:none;"{% endifequal %}
{% ifequal field.name "name" %} style="display:none;"{% endifequal %}
{% ifequal field.name "email" %} style="display:none;"{% endifequal %}
{% ifequal field.name "url" %} style="display:none;"{% endifequal %}
{% ifequal field.name "title" %} style="display:none;"{% endifequal %}>
<!-- {{ field.label_tag }} -->{{ field }}
</p>
{% endif %}
{% endfor %}
<p class="submit">
<!-- <button><input type="submit" name="post" value="{% trans "Send" %}" /></button> -->
<button type="submit">Send</button>
<!-- <input type="submit" name="preview" class="submit-preview" value="{% trans "Preview" %}" /> -->
</p>
</form>
Maybe you don't need to check for next variable in your template. You could try changing:
{% if next %}<input type="hidden" name="next" value="{{ next }}" />{% endif %}
to just:
<input type="hidden" name="next" value="/added/comment/page/" />
In case you use views.py, redirecting from there seems more obvious, at least for me, as it helps keep the concern away from the template:
from django.http import HttpResponseRedirect
HttpResponseRedirect("/path/to/redirect")
The problem with axel22's answer is that it requires a change to each template that requires the comment form - if you have multiple object types that can be commented on, this is not DRY.
Unfortunately, I'm also still looking for an answer that works.
if you are using {% render_comment_form for object %} tag in your template, just add something like {% url object's_named_view object.id as next %} or wrap it with {% with object.get_absolute_url as next %} ... {% endwith %} construction.
See my solution here: Django: Redirect to current article after comment post
It basically uses a view that's triggered by the comment post url which redirects back to the original referrer page.
I am using the Django comments framework in two places on my site. After each submission, I'd like for the user to just be redirected back to the original page they were on.
How do you define the "next" variable so the user is redirected?
Information on the redirect : http://docs.djangoproject.com/en/dev/ref/contrib/comments/#redirecting-after-the-comment-post
Also, here is the form I am using. The comment.types do not work, but that is what I think I am supposed to do - define two different next inputs for each comment type (picture vs meal).
{% load comments i18n %}
<form action="{% comment_form_target %}" method="post">{% csrf_token %}
{% if comment.type == '19' %}
<input type="hidden" name="next" value="{% url meal comment.object_pk %}" />
{% endif %}
{% if comment.type == '23' %}
<input type="hidden" name="next" value="{% url picture comment.object_pk %}" />
{% endif %}
<!-- <input type="hidden" name="next" value="{{ next }}" /> -->
{% for field in form %}
{% if field.is_hidden %}
{{ field }}
{% else %}
{% if field.errors %}{{ field.errors }}{% endif %}
<p
{% if field.errors %} class="error"{% endif %}
{% ifequal field.name "honeypot" %} style="display:none;"{% endifequal %}
{% ifequal field.name "name" %} style="display:none;"{% endifequal %}
{% ifequal field.name "email" %} style="display:none;"{% endifequal %}
{% ifequal field.name "url" %} style="display:none;"{% endifequal %}
{% ifequal field.name "title" %} style="display:none;"{% endifequal %}>
<!-- {{ field.label_tag }} -->{{ field }}
</p>
{% endif %}
{% endfor %}
<p class="submit">
<button type="submit">Send</button>
<!-- <input type="submit" name="preview" class="submit-preview" value="{% trans "Preview" %}" /> -->
</p>
</form>
And then on the Meal & Picture pages I have:
<h4>Post a Message</h4>
{% render_comment_form for meal %}
<h4>Post a Message</h4>
{% render_comment_form for picture %}
Figured it out. To use the next with multiple objects, use an if statement.
{% if picture %}
<input type="hidden" name="next" value="{% url picture picture.id %}" />
{% endif %}
If you want to stay on the same page ajax is an option, you could use something like django_ajaxcomments, there are quite a few posts on others ways to do this with ajax.
