Import / migrate old (Django 0.97) model data into Django 1.8 or higher
What would be the best approach to migrating or importing data from a very old Django app (0.97) to a relatively "modern" Django release (1.8)? The application (if you can call it that) is little more than a series of models and some simple views. The users primarily accessed it via the admin UI (I know, I know). So in terms of code to convert, there's very little. I've updated the models.py to be 1.8-friendly, and I can easily spin up an empty instance of the app without difficulty. However, I run into problems once I try to get the old data in the system. I thought I'd try dumpdata/loaddata, but didn't expect it to work (and it didn't). I get a number of errors along these lines: django.db.utils.IntegrityError: Problem installing fixture 'olddata.json': Could not load contenttypes.ContentType(pk=6): duplicate key value violates unique constraint "django_content_type_app_label_5fd9156b761d2158_uniq" DETAIL: Key (app_label, model)=(contenttypes, contenttype) already exists. Before I dive into the depths of the export file, I want to be sure that I'm on the right track. Is there a better way to do this? -
Opening Existing Django Project in Visual Studio
I've been using Jetbrains Pycharm for years, but lately the performance has been getting abysmal. I'd like to give Visual Studio a shot. So I cloned my main repo, through VS, and tried to setup a "Solution". It doesn't seem to recognize my project. In Pycharm I could just clone any old repo, open the folder and then select the interpreter/env I wanted to run it in. I've kinda got it working by creating a django project in VS and then loading all my files in, but that doesn't seem right or viable. Any tips on how to setup/create a "Solution" for a cloned django project? -

Django Nested Form - Always Showing Object instead of model details
I'm working on a Django project generated via Mezzanine. I've been able to create my models, however I want to have a form where an admin can select from a list to assign a value in a many to many or a one to many relationship. For example, I have a model for Schemas: class Schema(AutoCreatedUpdatedMixin, SoftDeleteMixin): """List of all Schemas in a given database""" name = models.CharField(max_length=128, null=False) status = models.BooleanField(max_length=128, null=False, default=True, verbose_name="Is Active") description = models.CharField(max_length=65535, null=True, blank=True, default=None) database = models.ForeignKey(Database, on_delete=models.CASCADE) pull_requests = models.ManyToManyField(Link) questions = models.ManyToManyField(Question, blank=True) comments = models.ManyToManyField(Comment, blank=True) technical_owners = models.ManyToManyField(Employee, related_name='technical_owners_schemas', blank=True) business_owners = models.ManyToManyField(Employee, related_name='business_owners_schemas', blank=True) watchers = models.ManyToManyField(Employee, related_name='watchers_schemas', blank=True) def __unicode__(self): return "{}".format(self.name) And I have a model for Employees class Employee(AutoCreatedUpdatedMixin, SoftDeleteMixin): """List of people with any involvement in tables or fields: business or technical owners, developers, etc""" name = models.CharField(max_length=256, blank=False, null=False, default=None, unique=True) email = models.EmailField(blank=True, null=True, unique=True) def __unicode__(self): return "{}".format(self.employee) An employee can own multiple schemas and a schema can be owned by multiple employees.

A confused about database structure and displacement on django admin
I am currently working on django and get confused about how to design the model. Right now, I have a table named 'Reactionmeta' which structure like below: 1 2 3 4 5 6 reaction name metabolite1 stoichiometry1 ....... metabolite60 stoichiometry60 (stoichiometry1 corresponds to metabolite1 and so on so forth) (P.S: I have to claim that each stoichiometry correspond to one metabolites in the reaction, like a + b -> 2c + d(the number is the stoichiometry) However, one metabolite may has different stoichiometry, because they may involved in different reactions. For example: a + 2b + c -> d + e + f; 2a + b -> h + j (metabolite a has different stoichiometry in two reactions) some of the reactions, contains 2 metabolites, thus this reaction have value in 6 columns and no value from column 7-122. And some of the reactions contains more than 40 metabolites, so they have values in majority of columns. My question is, I created the class and registered in the admin.py, and when I clicked on one reaction in adminsite and all the columns are displayed even though some of fields are blank, like below: In that case, how can only display … -

Django Forms: styling forms (checkboxes) manually - Input to be outside of label
I need to render checkbox form fields in the following format in html template: <input id="tag" type="checkbox" name="check" value="1"> <label for="tag">Tag 1</label> Currently, in my template I tried: {{ filter.form.tags.errors }} {% for field in filter.form.tags %} <input id="{{ field.id_for_label }}" type="checkbox" name="check"> <label for="{{ field.id_for_label }}">{{ field.value }}</label> {% endfor %} This will not render {{ field.value }} (I get empty instead of Tag 1) and also is non sticky. I also tried: {% for field in filter.form.tags %} {{ field.label_tag }} {{ field }} {% endfor %} Which gives me nested of <label><input></input></label>, but displays everything that I need. Is it possible to render a form such that I get the format that I'm after? (It should also preserve checked e.g. make ticks sticky). -
Daphne server gives "Exception Inside Application" and no other information
I'm trying to get my Django channels based project up and running. ./manage.py does the trick, but I'm attempting to start it using something like Heroku CLI, Foreman, or plain ol daphne config.asgi:application to get it running, since eventually I'll need it up on Heroku.

Importing defined functions from one .py file to another .py file in Django
So I am trying to create a website and I have my html working 100% on a local host using django. At the moment my code is not associated with the html so if I put in a username and password, the page does nothing, which makes sense. I am at the point where I am trying to import a defined function from my .py file with all my code(b.py) and I have another file (a.py) which essentially should take the information from the defined functions of b.py, use the information, then display it on the localhost webpage. But my issue is that it is saying *ImportError: cannot import name 'definedfunctionname'. Both a.py and b.py are in the same directory as eachother. -
Django multiple widgets in one modelform field
I have the following model and modelform: class Course(models.Model): duration = models.CharField(max_length=100, blank=True,null=True) class NewCourseForm(ModelForm): class Meta: model = Course fields = ['duration',] When rendering the form, I want the user to select a number, and time unit. E.g. 2 weeks. It should look something like: Duration <input type='number', name='duration_number'> <select name='duration_unit'> <option>Hours</option> <option>Days</option <option>Weeks</option> <option>Months</option> <option>Years</option> </select> In the view, I will combine these two values into a string e.g. '2 Weeks' which will be saved in the duration field. How can I get my modelform to render as above? I know I could make a separate table for the duration with a OneToOne relationship, but wont the join when performing lookups will slow things down ? -
Django: Image Resizing & Compression
I'm working on a django project in which users can upload images. Here's the view, class AllPictures(models.Model): profile = models.ImageField(upload_to='profile_image', blank=True) // But before saving the image i'm compressing & resizing it, here's how def save(self, *args, **kwargs): if self.profile: img = Image.open(self.profile) resize = img.resize((240, 240), Image.ANTIALIAS) new_image = BytesIO() resize.save(new_image, format=img.format, quality=75) temp_name = self.profile.name self.profile.save(temp_name, content=ContentFile(new_image.getvalue()), save=False) super(AllPictures, self).save(*args, **kwargs) But the problem is that when i upload images then instead of saving them directly inside the profile_image folder, it creates a long series of sub-sub-folders for every new image & saves that image inside a separate folder. So, the profile_image folder looks something like this, profile_image my_image.png ----profile_image new_image.png --------profile_image all_image.png ------------profile_image images.png ----------------profile_image picture.png --------------------profile_image another_pic.png & so on . . . How can we save all new images in just 1 folder & prevent the formation of these sub-folders? Thank You! -

Django custom User not registering with Admin
I've followed the documentation at https://docs.djangoproject.com/en/2.0/topics/auth/customizing/#substituting-a-custom-user-model, but for some reason things still aren't working for me. I can create and login to User accounts, but for some reason I can't view them with the admin. This leads me to believe they're not being registered correctly, but as said before, I've followed the documentation on how to do that: sign_up/models.py from django.contrib.auth.models import AbstractUser # Create your models here. class User(AbstractUser): pass sign_up/admin.py from django.contrib import admin from django.contrib.auth.admin import UserAdmin from .models import User # Register your models here. admin.register(User, UserAdmin) site/settings.py # define custom user model AUTH_USER_MODEL = 'sign_up.User' I've also tried deleting my database and migrations and reapplying them, but this still isn't helping. -

The problem come when i load my template (i use Python+Django), those value are listed in a tab : <table id="regnorme3Tab" name="regnorme3Tab" class="display" width="100%" cellspacing="0"> <thead> <tr> <th>ID</th> <th>Code</th> <th style="width:200px">Libellé</th> <th>Limite inf</th> <th>Valeur</th> <th>limite sup</th> </tr> </thead> <tbody> {% for reg_norme in reg_savs %} {%if reg_norme.Saisie == 'O' %} <tr name="Reg_Normes" id="{{reg_norme.regauxnormes}}"> <th><span> {{reg_norme.Id}}</span></th> <th class="codevalue"><span> {{reg_norme.Code}}</span></th> <th style="width:200px"><span> {{reg_norme.LibEtendu}}</span></th> <th><span> {{reg_norme.LimitInf}}</span></th> <th><span><input type="number" max="{{reg_norme.LimitSup}}" step="0.01" min="{{reg_norme.LimitInf}}"class="{{reg_norme.Code}}" id="{{reg_norme.Id}}" value="{{reg_norme.Valeur}}" required style="width:40px;"></span></th> <th><span> {{reg_norme.LimitSup}}</span></th> </tr> {%endif%} {% endfor %} </tbody> </table> If i leave things like that, nothing is displayed in my input, i had the same problem on some isolated number input and i managed to display the data by using parseFloat() and toFixed(2). document.getElementById('ebHumValue').value = parseFloat({{displayHUMHumidite}}).toFixed(2); So i though i would create a function with a loop on my tab and use parseFloat and toFixed to display something. $("#regnorme3Tab :input").each(function () { var number = this.name; this.value = number; alert(parseFloat(this.name).toFixed(2)); }); The function is in document.ready so it would format …
