Django-Filer: How to invoke upload widget outside admin - django

How do I invoke the upload widget outside Admin?
Using the standard form below does not work. The widget is corrupted.
forms.py
class PhotoAdd(forms.ModelForm):
class Meta:
model = Photo
fields = ('ImageFilerField',)
views.py
def photoadd(request):
context={}
context['form'] = PhotoAdd()
render(request, 'template.html', context)
template.html
{{ form }}
There is absolutely no reference to this in the documentation.
How can I upload photos outside admin?
Edit: (added generated code from django above)
<label for="id_doc_pic">Doc pic:</label>
</th>
<td>
<span class="filerFile">
<img id="id_doc_pic_thumbnail_img" src="/static/filer/icons/nofile_48x48.png" class="quiet" alt="no file selected" />
<span id="id_doc_pic_description_txt"></span>
<a href="/admin/filer/folder/last/?_to_field=file_ptr" class="related-lookup" id="lookup_id_doc_pic" title="Lookup">
<img src="/static/admin/img/icon_searchbox.png" width="16" height="16" alt="Lookup" /></a><img id="id_doc_pic_clear" class="filerClearer" src="/static/admin/img/icon_deletelink.gif" width="10" height="10" alt="Clear" title="Clear" style="display: none;" /><br />
<input class="vForeignKeyRawIdAdminField" id="id_doc_pic" name="doc_pic" type="text" />
<script type="text/javascript" id="id_doc_pic_javascript">
django.jQuery(document).ready(function(){
var plus = django.jQuery("#add_id_doc_pic");
if (plus.length){
plus.remove();
}
django.jQuery('#id_doc_pic_javascript').remove();
});
</script>
</span>
Javascript Error: "Uncaught ReferenceError: django is not defined"
Could it be that I need to know what css to include and what javascript files to load?

First of all, add {{ form.media }} in your html file, just after the tag <form> and {% csrf_token %}. Then extend the media class in your ModelForm of forms.py as explained by SteinRobert on Github issue: https://github.com/divio/django-cms/issues/6028. It works perfect! Thanks Stein!

Reverse for with no arguments not found for URL

I am attempting to create a view that allows users to delete a build log. On the view that shows the delete button with a link to the delete page I am getting the error
Reverse for 'build-log-delete' with no arguments not found. 1 pattern(s) tried: ['post/(?P<pk>[0-9]+)/build\\-log/(?P<pkz>[0-9]+)/delete$']
If I understand this error correctly its because I am not passing paramaters in the url.
<a class="delete-btn" href="{% url 'build-log-delete' %}">Delete</a>
However I do not understand why I need to pass parameters in the URL as I am not passing any new values into the URL and if so what parameters I would pass. Do I have to re pass the previous two?
urls
path('post/<int:pk>/build-log/<int:pkz>/', views.BuildLogDisplay, name='build-log-view'),
path('post/<int:pk>/build-log/<int:pkz>/delete', views.BuildLogDelete, name='build-log-delete') #error
views
def BuildLogDisplay(request, pk, pkz ):
post = BuildLog.objects.filter(post_id=pk)
log = BuildLog.objects.get(pk=pkz)
context = {
'post':post, 'log':log
}
return render(request, 'blog/buildlog.html', context)
def BuildLogDelete(request):
context = { }
return render(request, 'blog/BuildLogDelete.html', context)
full template
<div class="row">
<article class="cars-article">
<div class="flex">
<img class="rounded-circle article-img" src="{{ log.author.profile.image.url }}" />
<div>
<a class="article-title">{{ log.title }}</a>
</div>
</div>
<br>
<div>
{% if log.author == user %}
<a class="update-btn" href=""> Update</a>
<a class="delete-btn" href="{% url 'build-log-delete' %}">Delete</a>
{% endif %}
</div>
<hr class="solid">
<p class="article-content">{{ log.content | safe}}</p>
</article>
</div>
There are multiple errors in you code. You are not passing args in BuildLogDelete view but in url you are using those arguments. So the correct view should look like this.
def BuildLogDelete(request,pk,pkz):
# delete code
# write here
Next mistake which i can see is you are assigning queryset rather than object for the post key in BuildLogDisplay view. You should assign object.
post = BuildLog.objects.get(post_id=pk)
Lastly your original error mentioned in the question is because your build-log-delete url expects two arguments i.e pk and pkz but you haven't passed them in template. So it should be like this.
<a class="delete-btn" href='{% url "build-log-delete" pk=post.post_id pkz=log.pk %}'>Delete</a>
I would highly suggest you to look for already given generic views like ListView, TemplateView, CreateView, UpdateView and DeleteView. This will prevent you from reinventing the wheel

Send JSON from Places Autocomplete to Flask

I'm working on my very first web app utilizing the Google Places Autocomplete functionality in the frontend and Flask in the backend.
Current situation:
Whenever an address is selected from the autocomplete suggestions, a variable called 'address' is populated in the background containing the API response as JSON. Using a window alert I can confirm that this part works fine.
To-Do/ issue:
The address variable should be sent over to Flask so that I can do use it going forward.
Using AJAX to post the data however it never seems to reach Flask. The output is always None.
My best guess is that the submit button implemented after the Autocomplete stuff somehow overrides the JSON POST data in order to keep only the actual text which is in the form while submitting*.
Does that make sense? If yes, how can I still send the JSON data successfully? Or is the issue somewhere else?
I would appreciate any help.
Here is my code:
home.html
{% extends "base.html" %}
{% import 'bootstrap/wtf.html' as wtf %}
{% block app_content %}
{% from "_formhelpers.html" import render_field %}
<div class="container">
<form class="form form-horizontal" action="" method="post" role="form" novalidate>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=key&libraries=places&language=en"></script>
<script type="text/javascript">
google.maps.event.addDomListener(window, 'load', function () {
var autocomplete = new google.maps.places.Autocomplete(document.getElementById('autocomplete'),{
types: ['geocode']
});
// autocomplete.setFields('address_components');
google.maps.event.addListener(autocomplete, 'place_changed', function () {
var place = autocomplete.getPlace();
var address = place.address_components;
window.alert(JSON.stringify(address));
}
)})
$.ajax({
type: "POST",
url: "/",
data: address,
success: function(){},
dataType: "json",
contentType : "application/json"
});
</script>
<input type="text" id="autocomplete" size=50 style="width: 250px" placeholder="Enter your location" name=inputkiez>
<a href=# id=autocomplete><button class='btn btn-default'>Submit</button></a>
</form>
<div class="row">
or check out <a href='/result'> the latest reviews from others </a>
<div>
</div>
{% endblock %}
routes.py
#app.route('/', methods=['GET','POST'])
def search():
if request.method == 'POST':
jsdata = request.get_json()
flash('Data is: {}'.format(jsdata))
return redirect('/review')
return render_template('home.html')
#app.route('/review', methods=['GET', 'POST'])
def review():
reviewform = ReviewForm()
if reviewform.validate_on_submit():
userreview = Reviews(
reviewcriteria1= reviewform.reviewcriteria1.data,
reviewcriteria2= reviewform.reviewcriteria2.data,
reviewcriteria3= reviewform.reviewcriteria3.data,
)
db.session.add(userreview)
db.session.commit()
return redirect('/result')
return render_template('review.html', form=reviewform)
*The text in the form would include the address selected from Autocomplete but without any additional data obviously. I even managed to pass this text to the next page with request.form.to_dict() but this is not good enough for my use case since I also want at least the postal code to be sent over.
This is not the exact answer to my question but I found a way to send over the data to flask without having to bring in JSON/AJAX at all.
The trick is to send the data from the Autoplaces response as a hidden input of the form:
<form method="post" action="">
<input id="userinput" placeholder="Enter a location" type="text" name="name" class="form-control"><br>
<div id="map" style="height: 300px;width: 300px; float: none; margin: 0 auto;"></div><br>
<input type="hidden" name="address" id="address">
<input type="submit" name="submit" value="Submit" class="form-control btn btn-primary">
<div>or check out <a href='/result'> the latest reviews from others </a></div>
</form>
Then in routes.py you can easily get the data like this:
#app.route('/', methods=['GET','POST'])
def search():
if request.method == 'POST':
address = request.form['address']
# do something
This is basically a slightly modified version of the solution posted here (YT video).

django python form to submit, delete row from database and refresh page

I am newbie in Django and I would appreciate if someone can help me about this problem.
I have a database in backend with 100 rows of users information.
Name, surname, phone number.
The database is visible on Home page template and if you choose one of this names you can donate something to this person.
When you click on submit button will lead you to new ajax window where you input your data and then submit.
Then I got your message on email.
My questions is how to do at the same time to confirm (submit) and delete row from database (person from database) and then to refresh page ?
Meaning, when you submit form then function should delete person from Home page at once and have to refresh page so you can see another person ?
Here is the code.
I would appreciate any help.
Thanks to all.

sorry if I'm wrong but I understand that you want to do two actions.
In your code I can see that you have forms and class-based Views. Maybe you need to override the function form_valid to do the operations you need when you submit.
Check this website http://ccbv.co.uk there you will find the details of the views.
On click of submit hit the url & process your message on email part first and then you can delete the person from database by filtering out object of that particular person with whatever primary key you have for that table by writing a query in your view. and then render the remaining data of that table to your template on which you are Redirecting from your on submit click.
From above conversation what i understood that you don't want delete that person from database boolean field would be great option rather you want to save the message that has been sent from email by this way you can do both at the same time. you have the message saved in your database and from empty message data can render those user on template.

How do you dynamically display images in Django

I'm trying to dynamically display Images in Django. this is my details page
{% extends 'base.html' %}
{% load staticfiles %}

<div class="container">
<div class="row">
<div class="col-lg-8 col-lg-offset-2 col-md-10 col-md-offset-1">
<div class="page-heading">

<hr class="small">
<span class="subheading">blog detail</span>
</div>
</div>
</div>
</div>
</header>

So far I tried storing these approaches. I tried storing this in the database
{% static 'blog/img/about-bg.jpg' %}
and called it like this
style="background-image: url('{{ post.title }}')"
that didn't work. Then I tried storing it in the database like this
'blog/img/about-bg.jpg'
and calling it like this
style="background-image: url('{% static '{{ post.title }}' %}')
then I ried storing it like this in the database
static/blog/img/about-bg.jpg
and calling it like this
style="background-image: url('{{ post.title }}')"
I've also tried defining it in the views.py
pic = "path/pic.img"
context = {
"pic": pic
context and calling it
{{pic }}
none of these methods work. It's a little different from Laravel. In laravel
path/{{ post->title }}
would have worked. How can I do this in Django? any and all suggestions are welcome. To be clear I want all my articles to display an image on the index page, then when I click one of them, I am taken to the details page that image for that particular article is displayed
I've figured it out. It's supposed to be stored as
/static/blog/img/about-bg.jpg
not
static/blog/img/about-bg.jpg
the forward slash makes it work. in Laravel this does not matter
From you question I understand that by dynamically you mean that you want to upload an image to your site. So it's not just a static image that is always the same like a logo of your page or something.
You have to do this:
In models.py
from django.contrib.sites.models import Site
def generate_filename(filename): #it adds the image in a folder with the current year
ext = filename.split('.')[-1]
year = datetime.datetime.now().year
return str(year) + '/' + str(int(time())) + '.' + ext
class PageWithImage(models.Model):
image = models.ImageField(upload_to=generate_filename, blank=True, null=True)
site = models.ForeignKey(Site, blank=True, null=True)#this if you want the image linked with your site
Then in setting.py you have to add:
import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
MEDIA_ROOT = os.path.join(BASE_DIR, 'img')
MEDIA_URL = '/img/'
Then in the template:
<img itemprop="image" src="http://{{ object.site }}{{ object.image.url }}">
And don't forget to add the image field to admin.py
For adding images dynamically to your webpage using Django :
As we mostly use Jinja for templates,
<img src="{%static 'images/beach.svg' %}" alt="A beach image">
We give this kind of commands to access static image files. But for dynamic, we have to change the 'beach.svg' to something like {{dest2.img}} in the above HTML image tag, if my "views.py" function is like :
def index(request):
dest2 = Destination() // Imported class 'Destination()' from models.py .
dest2.name = 'Beach'
dest2.img = 'beach.svg' // The image name we need.
dest2.desc = 'Some beach description'
dest2.price = 2000
return render(request, 'index.html', {'dest2' : dest2}) // Passing the object value to html page.
If we logically think, the code should be like :
<img src="{%static 'images/{{dest2.img}}' %}" alt="A beach image"> // we cannot do this here!!!
We cannot use a Jinja code inside another Jinja code. So we add :
{% static 'images' as base_url %}
at the top of our HTML page. 'images' is the default folder for images and we are calling it as 'base_url' in this HTML page. So we have to use 'base_url' as path and 'dest2.img' as the file name. so the image source will be like :
<img src="{{base_url}}/{{dest2.img}}" alt="A beach image">
So finally we're done making the dynamic images in Django.!!!😋
First, you cannot use {% static 'blablabla' %} in CSS files.
Second, use this code:
style="background: url(/static/blog/img/about-bg.jpg) no-repeat"
Third, if you will be working with images from models in the future then your code should be:
style="background: url(/{{ your_object.your_img_field }}) no-repeat"

Existing forms:In Django

I have an pre-built HTML form and I need to reuse it with Django form class (django.forms), So how do I incorporate my HTML form with Django form class. for example
HTML:
<li id="foli11" class="">
<label class="desc" id="title11" for="Field11">
Username
<span id="req_0" class="req">*</span>
</label>
<div class="col">
<input id="Field11" name="Field11" type="text" class="field text medium" value="" maxlength="255" tabindex="11" />
</div>
</li>
How do I map this HTML in to Django form class, I know that it can be done by modifying Django form fields according to this HTML. But I guess it's a time consuming approach,so I would like to know that is there any easy and time saving solutions for this issue.
Thanks.
Extend the django forms.Form class and write to it your own form.as_my_ul similar to form.as_p:
Here is the implementation of as_p: http://code.djangoproject.com/browser/django/trunk/django/forms/forms.py#L227
def as_p(self):
"Returns this form rendered as HTML <p>s."
return self._html_output(
normal_row = u'<p%(html_class_attr)s>%(label)s %(field)s%(help_text)s</p>',
error_row = u'%s',
row_ender = '</p>',
help_text_html = u' %s',
errors_on_separate_row = True)
