What is best practice to handle related data with REST api and Vue
For example we use the models course and category Category Model entry { "id": 4, "slug": "", "name": "IT", "description": "", "parent": 0, "color": "red", "access_level": 1, "state": 1, "created_at": "2019-08-08T12:15:22Z", "updated_at": "2019-08-08T14:46:22.955028Z" } Course Model entry { "id": 1, "name": "“Herz trifft EKG” – Grundlagen der Anatomie und der EKG- 1", "company": 1, "categories": [ 4 ], "course_dates": [ 5, 6 ], "created_at": "2019-08-08T14:35:57.882390Z", "updated_at": "2019-08-08T14:47:44.858062Z" } In DRF i am using the ModelSerializer with which the Id´s are used to display the relation. Currently i am getting all data from courses and all categories and want to mutate the data in vue to "solve" the Id´s of the categories into the names. Is this best practice to handle multiple relations? My understanding is that all API endpoints should only return their simple data and not the related data but only the id´s. -
Is there a way to create number of list depending upon the int value of a variable?
For example, i=5 so list1, list2, list3, list4, list5 will be automatically generated based on input value provided by user. -
Unable to install pylint-django on mac
I'm trying to install the latest version of pylint-django. I have django 2 installed and updated, and I have built a site that is working fine, but an issue has cropped up with pylint. Whilst it has done a great job in vscode for the past 4 months, something seems to have changed and now pylint is notifying of issues that were never there previously on an unchanged file. Further research showed that django requires it's own version of linting that will ignore these issues correctly instead of just ignoring them, I'm assuming that it compensates for the framework in some way. I have tried to install using pip: pip install pylint-django but received the following error in response: (django_env) UKC02TQH6UHV22:pcc_django rki23$ pip install pylint-django Collecting pylint-django Using cached https://files.pythonhosted.org/packages/05/01/1e7241e247d544aed790391b3a3a4f0e2cd93b7604e5a50ef3323ce5a812/pylint-django-2.0.12.tar.gz Collecting pylint-plugin-utils>=0.5 (from pylint-django) Using cached https://files.pythonhosted.org/packages/5c/94/2f1a7a2468c42be1a57520e0a85953c5cef5f0672c5081c5e66f8d4a7d86/pylint-plugin-utils-0.6.tar.gz Collecting pylint>=2.0 (from pylint-django) Could not find a version that satisfies the requirement pylint>=2.0 (from pylint-django) (from versions: 0.15.2, 0.16.0, 0.18.0, 0.18.1, 0.19.0, 0.20.0, 0.21.0, 0.21.1, 0.21.2, 0.21.3, 0.22.0, 0.23.0, 0.24.0, 0.25.0, 0.25.1, 0.25.2, 0.26.0, 0.27.0, 0.28.0, 1.0.0, 1.1.0, 1.2.0, 1.2.1, 1.3.0, 1.3.1, 1.4.0, 1.4.1, 1.4.2, 1.4.3, 1.4.4, 1.4.5, 1.5.0, 1.5.1, 1.5.2, 1.5.3, 1.5.4, 1.5.5, 1.5.6, 1.6.0, 1.6.1, 1.6.2, 1.6.3, 1.6.4, 1.6.5, 1.7.0, … -
Multiple Choice Forms with Django
I'm new with Django and am trying to write the form, views, and templates code where a customer selects multiple choices and submits those, with random results from a database. I am struggling with the structure of the code. I am pretty sure I need CheckboxSelect Multiple, MultipleChoiceField or ModelMultipleChoiceField. The Django website discusses both but doesn't provide example templates as to how the code is structured. I am creating a questionnaire, that consists of selecting activity categories via various buttons, like a checkbox list, then based on that, a list of activities would populate on a different page - these activities would be random. Any help would be greatly appreciated. -

Django formset creating extra empty forms on GET and POST request?
I am learning to implement formset and I am using the django-formset plugin on the client side to dynamically add or remove forms. Now, here is my problem, I notice the extra empty form also gets submitted whenever I submit the formset due to which the updated value never passes validation as there is one empty form that gets submitted. What can I do such that the empty form is ignored and only the changed field value gets submitted for validation. def form_valid(self, form): context = self.get_context_data() print(context,type(context)) titles = context['formset'] self.object =form.save() if titles.is_valid(): if titles.has_changed(): print('title has changed') titles.instance = self.object titles.save() class SkillForm(forms.ModelForm): class Meta: model = Skill fields=('skill_name','level_of_proficiency',) SkillFormSet = inlineformset_factory( UserProfile, Skill, form=SkillForm, fields=['skill_name', 'level_of_proficiency'], can_delete=True,extra=1,max_num=5 ) -
Heroku Django setup install_requires from github
I have a heroku project that is trying to install a Django reusable app using pip install -r requirements.txt (it's not the exact command from the official heroku/python buildpack, but it's basically doing that). The problem is that my Django reusable app has a requirement itself, from a Github public repository. A few answers in pip install dependency links point to: The dependency-links syntax being not compatible with pip 19 The new syntax (i.e. package @ git+protocol://...) of course not being compatible with older versions of pip. My Django project can be deployed in different ways: Heroku, local, Docker (dev and prod). Most of these deployment methods have the latest version of pip. Heroku's python buildpack has Pip 9.0.2 My other deployment methods have Pip 19, so they have incompatibilities in the way they read requirements, and I can't have a method that works for both. For older versions of pip, I do in my setup.py: setup( # [...] install_requires=[ "my_package == x.y.z" ], dependency_links=["git+https://github.com/account/package/tarball/master#egg=my_package-x.y.z"] ) Whereas for Pip 19, I do: setup( # [...] install_requires=[ "my_package @ git+https://github.com/company/package.git" ], ) I tried forking the repo and just increasing the version to pip's latest version. It does work, except for … -

django-treebeard Node in a foreign key or many to many field: show tree visually correct?
Is there an easy solution for having a visually correct tree representation, when using a treebeard Node based model in a foreign key and/or many to many field? As far as I can tell for now, the tree is show as a flat list, but in the correct order. Also, I cannot find any specific widget or formfields, in the treebeard source and docs. Last, some research shows, that for example django-cms uses it's own solution, just prepending some white space, according to the node's depth. See django-cms source Any suggestions welcome. -
Foreign key field not POSTing on Django REST
So, i'm doing an API for a to-do task manager, and in this api i have a lot of tables that are related to one another (a Project belongs to a Client, a Client is a Person that belongs to a City, and so on) and i hope that by learning how to fix the example below, i'll be able to fix the rest of the tables, that have a similar problem. My problem is: a Person belongs to a City (that already exists), so one of the fields of Person is a ForeignKey to City, that i believe should be a Integer, the city id (Person lives in 1 city, City can home N people). But i can't get it to work. On the django /admin site, it all works perfectly. I can create the Person with his info and theres a select box with a list of every City and it works great. But when i try to POST using Postman or even the /api site, there used to be no field for the City id, now after googling and trying everything, i somehow added the City id field, but can't get it to work. The current problem … -

Unwanted behaviour of a html template when in use with django
I downloaded a free html/css/js template and wanted to run it on django. After fixing some of the directories for static files I managed to get it running. My problem is that some of the sliding elements are unusually extended and instead of being let's say 50px in height, they cover half of the page with nothing but blank. These elements also behave weirdly. If I inspect the element, for some reason all the proportions go back to normal, however when I click and drag the inspect element window up and down, the weirdly behaving elements extend and retract with the inspect element window. I'm relatively new to all this so I'm not even sure whether I should be looking through the html, css or the js files in order to find out why it does that. Could someone point me in the right direction please? This is what it looks like if I just run the html file Here I'm running it on django and you can see the elements extended Opening the inspect element window fixes the proportions Moving the inspect element window also moves the extended elements -

Django remove duplicates from .values_list query while preserving order
I have a model say MyModel which contains a CharField type. The model has a default meta ordering which should be preserved. I am using the following query to get the list of types - MyModel.objects.all().values_list('type', flat=True).distinct() However, the types are getting repeated. I can do .order_by('type').distinct() but that will change the ordering which I don't want. Is there any way to get the list of types in order without manually creating a list in python? Alternative faster solutions are also welcome. Django version - 1.11 -

Does Django's 'exact' field lookup perform a case-insensitive search?
From what I read on the Django manual, I thought that the exact field lookup would perform a case-SENSITIVE search, yet, when I do this FormZBaseElementExtraLabel.objects.filter(label__exact='his6') I get the following output <QuerySet [<FormZBaseElementExtraLabel: HIS6>]> clearly not case-sensitive, and in fact identical to the default filter or iexact. Any ideas as to what could be the problem? Thank you -

Can't find files in django
I'm trying to work with some json and csv files in my django project but it never found they. I created a static folder and inside it I have create a new one called data with the different files. But when I call it, the message is always the same, it can't found the path of my files. [Errno 2] File b'data/data.csv' does not exist: b'data/data.csv' Inside settings.py I have this: STATIC_URL = '/static/' STATICFILES_DIRS =[ os.path.join(BASE_DIR, 'static'), ] Somebody knows what I'm doing wrong? An example how I call my csv file: def dataframex(): data_csv = pd.read_csv('data/data.csv') print(data_csv) Thank you! -

Integrity Error in Django where project has two user table?
I am facing a problem in Django admin panel, when I want to add or delete or update any value I got this error, django.db.utils.IntegrityError: (1452, 'Cannot add or update a child row: a foreign key constraint fails (db_name.django_admin_log, CONSTRAINT django_admin_log_user_id_c564eba6_fk_auth_user_id FOREIGN KEY (user_id) REFERENCES auth_user (id))') In my project, there are two user tables, one that was created in the first migration after that I create a custom user model. It works fine in local but facing problems in the server. As Django used InnoDB by default all my table is in InnoDB (I find some solution like this if I convert the table engine to MyISAM it'll solve the problem), I have plenty of data in the database and I can't do any test operation in it.
