If else logic in controller
I have four buttons. Below are their html, <label>Severity *</label> <button class="btn btn-default btn-lg" ng-click="sModal()" name="s" ng-model="cpform.severity">{{cpform.severity}}</button> <label>Occurence *</label> <button class="btn btn-default btn-lg" ng-click="OModal()" name="o" ng-model="cpform.occurence">{{cpform.occurence}}</button> <label>Detection *</label> <button class="btn btn-default btn-lg" ng-click="siverifydetectionModal()" name="detection" ng-model="cpform.detection">{{cpform.detection}}</button> <label>RPN</label> <button class="btn btn-default btn-lg" ng-model="cpform.risk_score">{{cpform.severity*cpform.occurence*cpform.detection}}</button> All these 4 buttons are displayed in the modal. The values for the first three buttons are got from different modals. Here, I have displayed the Product value in the last button in RPN. When I tried to save the value, I was able to save the values of first three buttons except the last button value.

How to set attribute in option tag element in django form?
I'm trying to set <option> attribute in Django form.

List field input in django rest frameowrk browsable api - mongoengine
I have created a serializer that takes a list argument tags, but on the django-rest-framework browsable api, It doesn't seem to work. Code: Model class SocialFeed(Document): platform = StringField(max_length=20, required=True, choices=('facebook', 'twitter', 'instagram')) tags = ListField(default=None) created_at = DateTimeField(default=datetime.now(), required=True) Serializer class SocialFeedCreateSerializer(DocumentSerializer): class Meta: model = SocialFeed fields = [ 'id', 'platform', 'tags' ] View class SocialFeedCreateAPIView(CreateAPIView): queryset = SocialFeed.objects.all() serializer_class = SocialFeedCreateSerializer But on the browsable API, It shows a simple input box to enter tags, and I don't know what format should I put the tags in on the browsable API side, and I am not receving list of tags instead a string. If anybody has faced the same issue, please guide me. -

Django support static file for production

It become problem when I change DEBUG = False. I read this already but I don't understand. https://docs.djangoproject.com/en/1.10/howto/static-files/deployment/ I have read solution from here too. Why does DEBUG=False setting make my django Static Files Access fail? With debug turned off Django won't handle static files for you any more - your production web server (Apache or something) should take care of that. I wana try that. How shall I do? I don't want to run this since it is insecure. manage.py runserver --insecure -
Django REST calling reversed detail route cannot find kwargs
I'm implementing 'users/me/'. (I alse read the the article, but I'm try to add some specific function) I made a function in UserViewSet: @list_route() def me(self, request): # ... find user ... request.path = reverse('user-detail', kwargs={'pk': user.id}) self.partial_update(request) It raises AssertionError: Expected view UserViewSet to be called with a URL keyword argument named "pk". Fix your URL conf, or set the `.lookup_field` attribute on the view correctly. print(request.path) is /users/2/, so reverse is working. urls.py: router = routers.DefaultRouter() router.register(r'users', UserViewSet, base_name='user') How could I deliver a pk? I have no idea what is the mistake I made. -

Within Dango, how do I add a new value to request.POST data before saving?
I'm trying to allow the user to either manually enter a text field if they have the license info, or let it auto generate (based on form info) if its original content. I'm stuck because from my tests (using print command) the form is correctly updating with the information given in the form if LicenseTag field is left blank. The issue is that the updated information is not being saved in the database. After research this seems to be an issue of immutability, which is why I added request.POST.copy() and tested the commented out section defining mutability=True. Here's my views.py def STLupload(request): if request.method == 'POST': form = NewUpload(request.POST, request.FILES) data = request.POST.copy() if form.is_valid(): #Dis gona need alot of work firstname = request.user.first_name lastname = request.user.last_name displayname = request.user.display_name email = request.user.email if (firstname or lastname == "None"): if displayname == "None": liscname = email else: liscname = '%s %s' % (firstname, lastname) else: liscname = displayname filetitle = request.POST.get( 'Title' , '') lisc = '%s %s' % (filetitle, liscname) if data['LicenseTag'] == "": ''' mutable = request.POST._mutable request.POST._mutable = True request.POST['LicenseTag'] = lisc request.POST._mutable = mutable ''' data['LicenseTag'] = lisc print (request.POST.get( 'LicenseTag' , '')) print ("blank") else: … -
How to transfer data from Django to Ext JS

Django: extending models of other apps
I'm working on small ERP-like project on Django which contains different apps (Products, Sales, Purchases, Accounting, MRP, ...). A few of them are "base-level", while others have dependencies (for example, a Sales app requires the Products app). For the sake of modularity and loose-coupling, I'm trying to keep the apps as independent as possible: those with dependencies aren't allowed to modify the underlying data. However, it would be extremely useful and make things way simpler if the apps could extend (add fields) tables in the models of their dependencies (for instance, Sales would add a can_be_sold BooleanField in one of the tables within the scope of Products). This way when a user internally chooses to install an app, a setup function makes the required "upgrades" for it to integrate properly with the dependencies, while the user installs only what he needs without having to provide unnecessary or unrelated information. I thought of making one-to-one relationships with the dependencies, but this solution doesn't convince me because (a) it doesn't seem very efficient to make so many new tables for maybe one or two extra fields, and (b) working with forms and signals would be a hassle (making code harder to mantain … -
Difficulty Implementing TinyMCE for Form Fields

Django - get_or_create() with auto_now=True
I’m using Django and I'm having a problem with a Python script that uses Django models The script that I'm using takes data from an api and loads it into my database. my model: class Movie(models.Model): title = models.CharField(max_length=511) tmdb_id = models.IntegerField(null=True, blank=True) release = models.DateField(null=True, blank=True) poster = models.TextField(max_length=500, null=True) runtime = models.IntegerField(null=True, blank=True) description = models.TextField(null=True, blank=True) edit = models.DateTimeField(auto_now=True, null=True, blank=True) the script: movies = tmdb.Movies().upcoming() results = movies['results'] ids = [] for movie in results: data, created = Movie.objects.get_or_create(title=movie['title'], tmdb_id=movie['id'], release=movie['release_date'], description=movie['overview'], backdrop=movie['backdrop_path'], poster=movie['poster_path'], popularity=movie['popularity']) The problem I'm having is that whenever I run the script, the entries are duplicated because the edit field is change, but the purpose I put the edit field is to know when exactly a movie got edited, ie: some other field got changed. How can I avoid the duplicates, but also keep the edit field in case some real change happened? -
How can I update two models in one serializer in Django Rest Framework?
I have a database schema that has each object of a certain type being stored across two separate tables (one row in each table, different data in each, with a foreign key from one to the other.) Unfortunately, Django Rest Framework tends to assume that there is a one to one correspondence between serializers and models, which is not true of my case. How should I be approaching this? It seems like the serializer should return the representation of the object which will be the actual HTTP response of the ajax requests, so using two serializers doesn't seem right. I've looked at extending BaseSerializer (which is how I currently plan to implement this if I don't find better solutions), but certain methods take in an instance, which should contain all the data needed to serialize the object, whereas I have two instances relevant. Any advice would be super appreciated! Thank you. -
Django - How to Modularize a large web Application?
I'm trying to figure out the best way to build a large web application, but keeping the various logical sections modularized. For example, there will be a number of different logical sections: Estimates Work Orders Accounting Contacts etc... As much as possible, I want to have the code for each of these modules disconnected from all the other modules. If code from one section starts to throw errors or cause incorrect data, I don't want that to affect other modules. My first thought is just to separate by using Django 'apps'. Each module is its own app. Then, if I build each app to be "pluggable", then the code is self sufficient. However, the problem with this approach is that the modules will likely need to access the models of other modules. For example, the 'Accounting' module will need access to the 'Contacts' model, since we want to send invoices to people in our contacts list. I looked into having a completely separate Django project for each module, but that poses problems (I think) for user authentication. Plus, to my knowledge, multiple Django projects can't (easily) share one database. Just wondering if there are any good ways or best practices … -
Some Safari users get "Safari Can't Open the Page" on the first load
I've noticed that some of my users randmonly get "Safari Can't Open the Page" the very first time they load our application, which gets automatically fixed if they reload. Testing with a user with the problem, I found that it doesn't happen on Chrome or Firefox. Another oddity is that some links work, but others that have more functionality in them (auto-login from link, etc) will fail. The internet says that it could be a DNS issue, but that doesn't explain why Chrome works. What could be the culprit? We don't even have KeepAlive on as our load balancers handle that part and they're set to 60 seconds over there. -
Django. Access the foreign key fields in the template from a form object
I use Django 1.8.14. I have two models: class Event(models.Model): title = models.CharField(max_length=255,) date = models.DateTimeField() ... def __unicode__(self): return self.title class Card(models.Model): user = models.ForeignKey(MyUser, related_name="user") event = models.ForeignKey(Event,) ... Card model form: class CardForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(CardForm, self).__init__(*args, **kwargs) self.fields['event'].empty_label = None class Meta: model = Card fields = ('event', ) widgets = {'event': forms.RadioSelect, } I render form like this: <form method="POST"> {% csrf_token %} {% for choice in cardform.event %} {{ choice.tag }} {{ choice.choice_label }} {% endfor %} </form > In the label of each radio button I need to display both fields value "title" and "date" of Event model which is ForeignKey of Card. Now label includes only "title" value. What is the best way to do it? I tried {{ cardform.instance.event.date }} but it doesn't work.
