问题 I have a template called client_details.html that displays user , note and datetime . Now sometimes, a client may not have an entry for user, note and datetime. What my program will do instead is display None if these fields are empty. I do not want the to display None. If a field has no value I don't want to see any value e.g. let it be blank if possible instead of displaying None. views.py @login_required def get_client(request, client_id = 0): client = None try: client = models.Client

问题 Is it considered correct/ are there any pitfalls in returning partial templates to ajax POST requests? For example: if request.is_ajax: # response is just the form return render(request, 'contact/fields.html', {'form':form}) 回答1: The most typical approach is returning JSON and then contructing whatever HTML you need client-side from the JSON data. However, it could be argued that this is mixing presentation with behavior and it would be better to clearly separate out the HTML. On the flip

问题 So ultimately, what I'm doing is trying to upload and post multiple files to a Django backend using AngularJS. I can post a single file, but it seems like when a FileList object is put in the $http.post data field, the backend no longer detects any files in the POST request. Here's what the html looks like: <form enctype="multipart/form-data" action="upload" method="POST"> <div class="form-group"> <span class="btn btn-info btn-file"> <i class="glyphicon glyphicon-file"></i> Browse <input

问题 I have sensitive data (database passwords) in settings.py and I was advised to upload my Django project to a github repository before pushing it to Heroku on their "Getting Started with Django on Heroku". If I put settings.py in .gitignore, then presumably it won't get deployed with my project. How can I prevent settings.py from being exposed but still get it deployed with my project ? 回答1: You can use environment variables (with heroku config:add SECRET=my-secret ) to setup sensitive data

问题 I have a Django data model like this (data fields omitted): class Atom(Model): pass class State(Model): atom = ForeignKey(Atom) class Transition(Model): atom = ForeignKey(Atom) upstate = ForeignKey(State,related_name='uptrans') lostate = ForeignKey(State,related_name='lotrans') When I query, the fields to be restricted can be in either model, so it is easiest to query on Transition.objects.filter(...) since all fields in the other models can be reached through the foreign keys. Let's call the

问题 I have a small problem with User model, the model looks like this: #! -*- coding: utf-8 -*- from django.db import models from django.contrib.auth.models import User class UserProfile(models.Model): url = models.URLField(max_length = 70, blank = True, verbose_name = 'WWW') home_address = models.TextField(blank = True, verbose_name = 'Home Adress') user = models.ForeignKey(User, blank = True, unique = True) def __unicode__(self): return '%s' %(self.user) When I open a django-shell and first
