How can I access data sent in a post request in Django? - django

I have a form that is supposed to create a new 'Quote' record in Django. A 'Quote' requires a BookID for a foreign key.
This is my form
<form method="POST" action="{% url 'quotes:createQuote' %}">
{% csrf_token %}
<section>
<label for="q_text">Quote Text</label>
<input type="text" name="text" id="q_text" placeholder="Enter a Quote" style="padding-left:3px"> <br>
<label for="q_book">Book ID</label>
<input type="text" name="bookID" id="q_book" placeholder="Enter Book ID" style="padding-left:3px"> <br>
<label for="q_disp">Display Quote Now?</label>
<input type="radio" name="display" id="q_disp" value="True"> True
<input type="radio" name="display" value ="False">False <br>
<button value="submit">Submit</button>
</section>
</form>
And this is the method that it is targeting
def createQuote(request):
#b = get_object_or_404(Book, pk=request.bookID)
return HttpResponseRedirect(reverse('quotes:index'))
Somewhere in that request argument I assume there is some sort of field that contains the bookID the user will pass in on the form. How do I get at that information?
Bonus points for anyone who can tell me some way I can visualise data like I might with console.log(some.collection) in Javascript

if request.method == "POST":
book_id = request.POST['book_id']
Assuming you're sure it's in there. Otherwise you'll need to verify/provide a default value like you would for a normal python dictionary.
As for visualising the data, do you mean printing it to the console? In which case if you're running the django runserver you can just do print some_data. If you want it formatted a little nicer, you can use pretty print:
import pprint
pp = pprint.PrettyPrinter()
pp.pprint(some_data)

django CMS don't show toolbar on login

I'm looking for a way to not automatically show the CMS toolbar (version 3.3.0) when a 'staff-user' logs in.
The toolbar should only be activated when ?edit is in the URL.
The documentation mentions the CMS_TOOLBAR_HIDE option, but I don't see any effects when enabled. Also the description:
"If True, the toolbar is hidden in the pages out django CMS."
seems not totally clear to me...
Any ideas?
If you add ?toolbar_off to the URL the toolbar disappears completely (no toggle button). ?edit turns it back on.
To automatically turn it off:
(A) You'd could add something like a middleware or hook into the login chain and add the parameter there.
(B) You might subclass/extend the CMSToolbar to override the following default behavior:
def init_toolbar(self, request):
self.request = request
self.is_staff = self.request.user.is_staff
self.edit_mode = self.is_staff and self.request.session.get('cms_edit', False)
self.show_toolbar = self.is_staff or self.request.session.get('cms_edit', False)
if self.request.session.get('cms_toolbar_disabled', False):
self.show_toolbar = False
Especially the last lines would have to be changed to use a default of True:
if self.request.session.get('cms_toolbar_disabled', True):
self.show_toolbar = False
I have overridden the login.html and adding a trailing ?toolbar_off to the {{ next }} hidden input value.
<form action="{{ app_path }}" method="post" id="login-form">{% csrf_token %}
<div class="form-element-wrapper">
<input class="form-input" type="text" name="username" autofocus="" maxlength="254"
required="" id="id_username" data-cip-id="id_username">
<span class="form-input-highlight"></span>
<span class="form-input-bar"></span>
<label for="username" class="form-label">Username</label>
</div>
<div class="form-element-wrapper">
<input class="form-input [% password_css %]" type="password" name="password" required=""
id="id_password" data-cip-id="id_password">
<span class="form-input-highlight"></span>
<span class="form-input-bar"></span>
<label for="password" class="form-label">Passwort</label>
<!-- THIS IS THE IMPORTANT LINE! -->
<input type="hidden" name="next" value="{{ next }}?toolbar_off"/>
</div>
<div class="form-element-wrapper">
<button class="form-element form-button" type="submit"
value="{% trans 'Log in' %}">{% trans 'Log in' %}</button>
</div>
</form>
Just a little solution if a user signs in via the login page. This does not affect the login via ?edit.

Use form information in external POST request

I've built a simple form to open up a JIRA ticket based on user input. I've almost got all of it, except I don't know how to use the form element in the POST request. Here's what I have so far:
<form target="_blank" action='http://baseurl.com/secure/CreateIssueDetails!init.jspa?pid=10517&issuetype=3&summary=Change+application+name+to+{{new_name}}&reporter={{request.user}}&priority=5&assignee=xxx' method='post'>
<label for="new_name">New name: </label>
<input id="new_name" type="text" name="new_name" value="{{item.name}}">
<input type="submit" value="Create JIRA ticket">
</form>
So I just need the value the user puts in the new_name element to be passed into the appropriate spot in the URL. How do I access that?
It sounds like you're getting POST and GET mixed. POST data would not be included in the URL itself, but rather in the request payload itself.
So, your URL would be http://baseurl.com/secure/CreateIssueDetails!init.jspa
The payload would be separately put in the body of the HTTP request.
If you need to use a GET method, the URL itself would be the same as above, but the URL that eventually gets hit would be http://baseurl.com/secure/CreateIssueDetails!init.jspa?new_name=WHATEVERVALUE.
If you need additional key-value pairs to get passed, just add them as hidden fields and pass them that way.
Your code, edited:
<form target="_blank" action='http://baseurl.com/secure/CreateIssueDetails!init.jspa' method='post'> <!-- ARE YOU SURE IT'S A POST REQUEST AND NOT A GET? -->
<label for="new_name">New name: </label>
<input id="new_name" type="text" name="new_name" value="{{item.name}}">
<input type="hidden" value="10517" name="pid">
<input type="hidden" value="3" name="issuetype">
<input type="hidden" value="5" name="priority">
<input type="hidden" value="Change application name to {{new_name}}" name="summary">
<input type="hidden" value="{{request.user}}" name="reporter">
<input type="hidden" value="xxx" name="assignee">
<input type="submit" value="Create JIRA ticket">
</form>
Makes sense?

Display the post data after error in django and html5

django form
{% for field in form.fields %}
{{field}}
</div>
{% endfor %}
If there is an error {{field.email}} will output this html with a post data value
<input id="id_email" type="text" value="gffdg" />
I want to use HTML 5 inputs but don't know how to get the post value if there is error
<input id="id_email" type="email" >
edit..
I was hoping not to use widgets with my django forms and just type the html5 code in my template (type="email" not type="text")
<input id="id_email" type="email" >`
but can't figure out how to get the value back after a post with errors.
<input value="?????" />
If you are trying to get the bound value of the email field, then the following template code should work:
<input id="id_email" type="email" value="{{ form.email.value }}">
If the value is not set, then it will be a blank field.

How to make Chrome respect the names of my fields and not attempt to autocomplete

I have two different forms on my home page: one for logins and one for registrations. As you can see from the code, the forms have inputs with different names:
<h3> Log In </h3>
<form action="/login/" method="POST" class="form-vertical" style="padding-top: 5px">
<input id="id_login_username" type="text" name="login_username" maxlength="25" />
<input type="password" name="login_password" id="id_login_password" /><br>
<button type="submit" class="btn btn-info">Login</button>
</form>
<h3> Sign Up <small>(It's free!)</small></h3>
<form action="/register/" method="POST" class="form-vertical" style="padding-top: 5px">
<input id="id_register_username" type="text" name="register_username" maxlength="25" />
<input type="text" name="register_email" id="id_register_email" />
<input type="password" name="register_password" id="id_register_password" />
<input type="password" name="register_password2" id="id_register_password2" /><br>
<button type="submit" class="btn">Submit</button>
</form>
Which renders to this in Chrome:
What can be causing this? And how can I fix it?
That's a really good question and I'm sorry to say I have no idea. Did
you try to register once and also login at least once? If so, that
"might" be what's causing it as browsers come complete with the
"autoremember" feature.
Assuming autofill is enabled (it is by default), the reason it autofills the rest is because chrome's autofill server works on regular expressions, not exact matches.
All the regular expressions used for the various fields can be found in autofill_regex_constants.cc.utf8.
From there you can see that the expression for email field is "e.?mail" and for username it is "user.?name|user.?id|nickname|maiden name|title|prefix|suffix"
It appears a similar question has been asked before:
What is the correct way to stop form input boxes auto-completing?
There is an autocomplete attribute you can use in form fields.
<input id="id_login_username" type="text" name="login_username" maxlength="25" autocomplete="off" />

How to translate a form in django

I have a form in a django site
<form method="POST" action="." class="right_custom">{% csrf_token %}
<br>{% trans "Enter the discount coupon code if you have any" %}</br>
<input type="text" name="coupon_code" size="25" maxlength="25" />
<input type="submit" name="submit" value="Caluclate Discount"/>
</form>
I would like to translate the entire site to a lot of languages. I need to translate the button text which is Caluclate Discount. How can I do that? if i use {% trans %} tag, how will the view catch the right post request?
UPDATE
There are many forms on the same page like this and my view uses if postdata['submit']=="Caluclate Discount" to determine which submit request it is.
I was able to get the translation working.
Thanks to the answers by #linux-warrior and #Joachim
Now the form is
<form method="POST" action="." class="right_custom">{% csrf_token %}
<input type="hidden" name="form_name" value="discount_form" />
<br>{% trans "Enter the discount coupon code if you have any" %}</br>
<input type="text" name="coupon_code" size="25" maxlength="25" />
<input type="submit" name="submit" value="{% trans "Caluclate Discount" %}" />
</form>
And i check for if postdata['form_name']=='discount_form' in my view
For buttons, you really don't use the value field for anything else than the button text, so it is straightforward to translate:
<input type="submit" name="submit" value="{% trans "Caluclate Discount" %}"/>
I think that you should use {% trans %} for submit "value". I don't understand why would you need that value inside your view. If you want, you can still give your submit input a custom "name" attribute.
Edit. By the way, your
<br>...</br>
thing inside your form appears to be a bug. You will probably want to make it
<p>...</p>
instead. It is also not recommended to use "submit" name for a type="submit" input (taken from http://api.jquery.com/submit/):
Forms and their child elements should not use input names or ids that conflict with properties of a form, such as submit, length, or method. Name conflicts can cause confusing failures. For a complete list of rules and to check your markup for these problems, see DOMLint.
Your view doesn't care about what is the submit button's value, so even if you translate it, your view function will work.
