Hashed password becomes the real password
When I try to change user's field in the django admin and then I save it, the hashed password ends up becoming the true password. So, If the password is hashed like this pbkdf2adhfkhadqeqerqfavghhfyb, and I change another field in the users model, this hashed password becomes my not hashed password. My code is like this. class UserCreationForm(forms.ModelForm): class Meta: model = User fields = ('Email','name','password','is_staff','is_superuser','Teacher', 'Student', 'Data_Joined', 'Is_active') def save(self, commit=True): user = super(UserCreationForm, self).save(commit=False) user.set_password(self.cleaned_data["password"]) if commit: user.save() return user class UserAdmin(admin.ModelAdmin): form = UserCreationForm admin.site.register(User, UserAdmin) -
Foreign Key Not Setting On CSV Upload -- Django
When importing csv to django the foreign keys are not setting. May code may be wrong. I am able to import the foreign keys but I am not able set them in the product object.

Inconsistent NoReverseMatch in Django1.10
Okay like so many relatively new Django developers I am running into a NoReverseMatch error that I cannot pin down. However, in this case I have namespaced my url patterns (they're a honking great idea) and, what is more, the template renders just fine when it's run on the built in Dev server but I get the errors when serving it with Apache on a separate machine. I am nonetheless hopeful that the answer is relatively simple. I have the following troublesome url patterns in urls.py app_name="coeffs" urlpatterns=[ ... url(r'^monthly/del_month/(?P<myid>[0-9]+)/$',views.del_month,name='del_month'), url(r'^item/del_item(?P<myid[0-9]+)/$'.views.del_item,name='del_item'), ] This is then translated in the my template file for a Delete Record button in the following manner (the class stuff is both Bootstrap formatting and some custom JQuery functions). Template.py <button type="button" class="btn btn-danger postAJAX" post-url="{% url 'coeffs:del_month' myid=c.id %}" name="button">Delete</button> However, when I attempt to render template.py I get the all too familiar error: Request Method: GET Request URL: http://192.168.2.40:8888/coeffs/monthly/ Django Version: 1.10.5 Exception Type: NoReverseMatch Exception Value: Reverse for 'del_month' with arguments '()' and keyword arguments '{'myid': 47}' not found. 0 pattern(s) tried: [] Using the interactive shell and those handy dandy error pages, I entered the exact commands specified in the defaulttag.py script: try: … -
Django: relate model to another which is related too
I have three models in Django: class One(models.Model): models.ForeignKey("self", primary_key=True) name = models.CharField(max_length=200) class Two(models.Model): one= models.ForeignKey(One) name = models.CharField(max_length=200) class Three(models.Model): one= models.ForeignKey(One) two = models.ForeignKey(Two) name = models.CharField(max_length=200) In the application I get operational Error: no such column: project_three.one_id I assume that this is because Three I want to relate to Two which already has relation to One. I just dont know how to solve this. I have not even found an example of such situation in the internet. Maybe I do it wrong? Can you help? -
Django Rest Framework Nested Routes - PK alternatives
I am using drf-nested-routers to nest my resources and everything is working well. I would like, however, to use something other than the pk to refer to a parent object. What I currently have is: api/movies/4/scenes - generates a list of scenes from movie with pk=4. What I would like is: api/movies/ghost-busters/scenes - where the identifier is movie.title instead of movie.pk Any suggestions? Thanks -

jQuery filter after ajax call (infinte scroll)
I've been working on this for a couple weeks now and I just can't get my head around it. I would really appreciate some help. Some background: I'm building a Django app that shows articles to the user. The user has keywords and only articles with these keywords are shown. The user can also set filters in order to see only the keywords of his choice. The filter after clicking one of the keywords works fine. But after adding the infinite scroll, I want to call my filter function every time the ajax call is made. But I can't get it to work, keywords are not filtered once the articles appear. Here is my code: html: <!-- Keyword list --> <div class="keyword_list"> <ul id="keywords"> <li class="keyword_div"><a href="#" role='button' class="popUp" data-href="{% url 'accounts:new_keyword' %}">+ Add keyword</a></li> {% for keyword in keywords %} <li class="keyword_div"> <a class="key" href="#">{{ keyword }}</a> <a href="#" class="popUp" data-href="{% url 'accounts:keyword_detail' keyword.pk %}"><i class="fa fa-cog" aria-hidden="true"></i></a> <a href="{% url 'accounts:keyword_delete' keyword.pk %}"><i class="fa fa-trash" aria-hidden="true"></i></a> </li> {% endfor %} </ul> </div> {% for article in article_list %} <div class="row article_div" id="article_div"> <div class="page-header col-xs-6 col-xs-offset-3 col-sm-6 col-sm-offset-3 col-lg-6 col-lg-offset-3"> <div class = "article_info"> <img src= "{{ article.website.avatar … -

I work on 2 files say ba.py and 2.py ba.py: import sys count = 1 # This is global count def callme(): pass # Doing Some operation 2.py import ba print ba.count ## This is working fine ba.callme() ## This is also working fine. But Iam running a automation job like this for i in $(find /home/some/SomeElse/HeyMore -type f);do python 2.py $i;done what this command do is takes the files from the folder specified and pass it argument to 2.py function.Now internally i want to open the file in python and do some operation.But i dont want to load my system so after 10 jobs i want to sleep for 10 seconds.So iam maintaining count =1 in ba.py script and after it is called for the first time it should be incremented to 2 and so on.. But when it hits 10 it should sleep as my logic is written below. print ba.count ba.count = ba.count + 1 ## Here increment should happen if ba.count % 10 == 0: time.sleep(10) else: ba.callme() Everytime i run this automation script i see only 1's and the script is not sleeping after 10 seconds.

Iterate Slugify In Django. For multiple objects named the same
I would like to be able to change the slug using slugify if the slug already exist. This site will have multiple products named the same but when you call the product using get_object_or_404 you will get an error because two or more objects are being called at one time.

Multiple select in wagtail admin
When using Django ModelAdmin, I can use: filter_horizontal = ('some_many_to_many_field',) So that, instead of showing the default multiple select widget, it shows a nice interface with two blocks for selecting some values. I have a model that is included in wagtailadmin, is there a similar option for using the same widget as in django ModelAdmin for my many-to-many fields? Thank you! -
Django - Collapse and Dropdown not working in bootstrap
I'm trying to implement bootstrap in my django project. When i'm trying to use javascript tagged objects those objects doesn't work. Tried so far: adding static js/bootstrap.js from static, trying bootstrap.css and bootstrap.min.css instead of my theme, copy-pasting other bootstrap.js sources and jquery sources.

Django Rest Framework: Nested serializers returning a dictionary but list is desired
I am trying to implement a basic Question Answer app. Here is my Questions model: class Questions(models.Model): created = models.DateTimeField(auto_now_add=True) question = models.CharField(max_length=1000, blank=True, default='') asked_by = models.ForeignKey(User, related_name='question_user', null=True, default=None, on_delete=models.CASCADE) upvote_by = models.ManyToManyField(User, default=None, related_name='advicesv1_upvote_question') Now, I want to send the usernames/first_names of the people in 'asked_by' and 'upvote_by' instead of ids which is sent by default. To implement this I used a nested serializer like this: class QuesUserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('username',) class NewQuestionSerializer(serializers.ModelSerializer): question_id = serializers.IntegerField(source='id', required=False) asked_by = QuesUserSerializer(read_only=True) upvote_by = QuesUserSerializer(many=True, read_only=True) class Meta: model = Questions fields = ('question_id', 'created', 'question', 'asked_by', 'upvote_by',) due to this, my current response is like this: { "question_id": 182, "created": "2017-03-07T10:53:16.241533Z", "question": "hey what's up?", "asked_by": { "username": "testuser141" }, "upvote_by": [ { "username": "testuser" }, { "username": "testuser1" } ] }, But my desired response is: { "question_id": 182, "created": "2017-03-07T10:53:16.241533Z", "question": "hey what's up?", "asked_by": "testuser141", "upvote_by": ["testuser", "testuser1",....], }, What is the best way to achieve this using django restframework serializers? -

Django utilizing other databases
I have two servers: server1, server2. Django is on server1 but connects to its database on server2. Server2 also hosts other databases.

Is it possible, in Django with Mongo (using pymongo) as a back end for data, to build nested formsets?
I would like to build a set of nested forms with Django and I believe I will have to use nested inline formsets, but nothing like that is covered in the documentation. This is a simple diagram of what I intend to build: Classes(form)-->Person1(form)-->Profile1 -->Person2(form) Attributes1 ... ... -->PersonN(form) ProfileN AttributesN So the relationship is: There is one Class. Classes can have many Persons. Each Person can have many (Profile + Attributes) I'm using Django 1.10 and Mongo (pyMongo). -
