You have a few options: Put different URLs in the action for the two forms. Then you’ll have two different view functions to deal with the two different forms. Read the submit button values from the POST data. You can tell which submit button was clicked: How can I build multiple submit buttons django form?
Essentially, you want to override the __init__ method of models.Model so that you keep a copy of the original value. This makes it so that you don’t have to do another DB lookup (which is always a good thing). class Person(models.Model): name = models.CharField() __original_name = None def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.__original_name = … Read more
When a URL is like domain/search/?q=haha, you would use request.GET.get(‘q’, ”). q is the parameter you want, and ” is the default value if q isn’t found. However, if you are instead just configuring your URLconf**, then your captures from the regex are passed to the function as arguments (or named arguments). Such as: (r’^user/(?P<username>\w{0,50})/$’, … Read more
If you still need to server static locally (e.g. for testing without debug) you can run devserver in insecure mode: manage.py runserver –insecure
As pointed out in this answer, Django 1.9 added the Field.disabled attribute: The disabled boolean argument, when set to True, disables a form field using the disabled HTML attribute so that it won’t be editable by users. Even if a user tampers with the field’s value submitted to the server, it will be ignored in … Read more
This is how I do it, using jQuery: My template: <h3>My Services</h3> {{ serviceFormset.management_form }} {% for form in serviceFormset.forms %} <div class=”table”> <table class=”no_error”> {{ form.as_table }} </table> </div> {% endfor %} <input type=”button” value=”Add More” id=”add_more”> <script> $(‘#add_more’).click(function() { cloneMore(‘div.table:last’, ‘service’); }); </script> In a javascript file: function cloneMore(selector, type) { var newElement … Read more
I’ve used a simple technique that works nicely for small cases with no special tags and no additional context. Sometimes this comes in handy {% for i in ‘0123456789’|make_list %} {{ forloop.counter }} {% endfor %}
Phew, Django documentation really does not have good example about this. I spent over 2 hours to dig up all the pieces to understand how this works. With that knowledge I implemented a project that makes possible to upload files and show them as list. To download source for the project, visit https://github.com/axelpale/minimal-django-file-upload-example or clone … Read more
The least painful and indeed Django-recommended way of doing this is through a OneToOneField(User) property. Extending the existing User model … If you wish to store information related to User, you can use a one-to-one relationship to a model containing the fields for additional information. This one-to-one model is often called a profile model, as … Read more
Concatenating the querysets into a list is the simplest approach. If the database will be hit for all querysets anyway (e.g. because the result needs to be sorted), this won’t add further cost. from itertools import chain result_list = list(chain(page_list, article_list, post_list)) Using itertools.chain is faster than looping each list and appending elements one by … Read more
