django template exceptions handling - django

All,
There is a template say x.html
its contes are
<form action ="/lookinto/a">
<p >name:</td><td> <input type="text" id=name" name="name"></input></p></tr>
<tr><td>
<p >Section:</td><td> <input type="text" id="section" name="section"></input></p></td></tr>
</form>
My question is that when handling,/lookinto/a if i have an exception how to send the data back to x.html
i.e, if name is xx and while saving there is a error how is xx sent back to x.html from views.
Thanks......

Use Django's forms framework.

Bootstrap for Django form: break down the fields of the form to 3 pages

I have a Django form, which has a lot of fields so that I have to break it up to 3 pages. It means user has to fill some fields of the form in one page , and then they click next to go to next pages and continue to fill the forms.
To achieve that, I plan to display some fields of the form on each page.
I have come up with this code:
HTML Page 1:
<form method="POST" action="#" class="form">
{{form.email}}
{{form.phone_number}} ...
</form>
HTML Page 2 :
<form method="POST" action="#" class="form">
{{form.current_job}}
{{form.current_salary}}...
</form>
It works fine with this code but it just shows the form in basic appearance, I would like to use bootstrap to make it more beautiful.
My questions is that, how can I integrate bootstrap ?
I have come up with this solution, but it is hard-coded and difficult if I changes fields of the form in the future:
<label class="control-label" for="id_field1">Field 1</label>
<input class="form-control" id="id_field1" maxlength="50" name="field1" type="text"/>
<label class="control-label" for="id_field2">Field 2</label>
<input class="form-control" id="id_field2" maxlength="50" name="field2" type="text"/>
Thank you for your help!

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 can I access data sent in a post request in 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)

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" />
