How to prevent PyCharm debugger from restarting on code changes?
While debugging in PyCharm with a Django project, if I add a break point, and then edit a line of code, let's say something simple like x = 2, the debugger will automatically terminate and restart. Is there a way to prevent this? Obviously a restart is needed to rerun code, but it would be nice to walk through break points and add code as I go without starting from the beginning. -
How do I make form entries mirror eachother?
Hi so I am working with angular2 javascript for my django app and I was wondering if there was any way that I could make my two form entries mirror eachother? This is what I have so far: <input class="form-control" ng-model="price_level.price_point[1].edit_price_per_case" name="price_per_case1" type="text" min="0" ng-pattern="/^[0-9]*(\.[0-9]{1,2})?$/" required style="width: 65px;"> <span ng-show="price_level.edit"> <input class="form-control" type="text" min="0" ng-pattern="/^[0-9]*(\.[0-9]{1,2})?$/" name="price_per_case0" ng-model="price_level.price_point[0].edit_price_per_case" ng-required='price_level.edit' style="width: 65px;"> </span> I would like it so that when I enter the top input it auto fills the bottom input or even vice versa. -
Override django user with AUTH_USER_MODEL
I have override the default User model in my app with AUTH_USER_MODEL. Here is the user model I want to use in my app, which is tied closely to a legacy database: from django.contrib.auth.models import AbstractUser from django.db import models class User(AbstractUser): name = models.CharField(max_length=128, blank=True) email = models.EmailField(unique=True) password = models.CharField(max_length=128) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) date_joined = models.DateTimeField(default=timezone.now) normalized_email = models.EmailField(unique=True) However, django complains that fields such as first_name, last_name, etc. are not provided. Is there a way to remove some of the existing fields in the User model? Or does specifying a custom user model only allow you to add additional fields on top of that? Is there a simple way to delete them, or do I basically have to add those fields (and ignore them) in order to use the django User? -
Django template variable not recognized in script tag but recognized in regular h1 tag. what could cause that?

Django + VueJS + RestAPI Based Project Guideline
Hello Devs :) WHO I'M & WHAT I WANT TO ACHIEVE ? I'm teen boy working on an Open Source Project (now, it's just in my pc), this project is my dream project & i'm working on this from months. Basically this is sort of Social Media Platform but not exactly a Social Media, it's for Creators & Professionals of Art, Tech, Writing, Journalism etc fields. It's just rough idea basically want to clear on which kind of project i'm working. PROGRESS I complete the design section using HTML5, CSS3, Bootstrap4, little JS Core, little JQuery. REMAINING Now the Backend part, in past i worked in PHP alot, but now i want to work in something new and interesting, so i choose, Python Django, but here i know that there is something called SPA & Front-End JS Framework (basically i know about it but never worked in it, but in JS, i did), which gives me a push and interest to learn and work in, i searched alot and finally choose VueJS, because it's lightweight and easy to learn & work. I learned that both Backend & Frontend would be separate and will be connected using RestAPI, which i found … -
Django Pass Model Field as Parameter to URL Stored in Another Model
I have three models: class Entity(models.Model): entity = models.CharField(primary_key=True, max_length=25) class Report(models.Model): report = models.CharField(max_length=50) report_link = models.CharField(max_length=300) class Item(models.Model): entities = models.ManyToManyField(Entity, related_name='entities') report = models.ForeginKey(Report) A view is built off of the Item model: def activity_list(request): items = Item.objects.select_related('report').prefetch_related('entities') return render(request, 'items/item_list.html', {'items':items}) This view gets routed to a template: {% for item in items %} <tr> <td> {% for entity in item.entities.all %} {{ entity }}{% if not forloop.last %}, {% endif %} {% endfor %} </td> <td>{{ item.report }}</td> <td>{{ item.report.report_link|urlize }}</td> </tr> {% endfor %} This line (<td>{{ item.report.report_link|urlize }}</td>) manifests like this in the browser: https://server.domain/reports/specificReport?entity= How would I pass the entities into the URL to filter the report? The desired result would look like this: https://server.domain/reports/specificReport?entity=12345 ...or if there are multiple entities for one item: https://server.domain/reports/specificReport?entity=12345,56789 Each report in the Report model has a link, but the link does not necessarily take the entity parameter, so it wouldn't be ideal to globally change all links (i.e. through jQuery or some other JS). However, there is JS running on this page, so it is possible to use that...although I think a Django option might be best. One thing I've thought about is adding an … -

Segmentation fault when database is there
I am using django2.1 and trying to set up a local mysql connection. The database is local and on, however I run into a Segmentation Fault error whenever trying to connect: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'file', 'USER': 'root', 'PASSWORD': '', 'HOST': '127.0.0.1', 'PORT': '3306', } } I know these settings are valid because I'm currently connecting to the same db with the same django settings in another app (using django 1.4). Django==2.1.2 mysqlclient==1.3.13 pytz==2018.5 The strange thing is, it does show a valid mysql error if I try and connect to the wrong db: django.db.utils.OperationalError: (1049, "Unknown database 'bad-database'") But if I enter in the correct db, it gives me this error: Segmentation fault: 11 Is there a way to fix this? -

Django template is not rendering vuejs components even if vue js files are injected
I am trying to inject vuejs components inside my django's base template, but unfortunately, the components are not getting rendered. Even though necessary vuejs js files are there. So, I am injecting the vuejs build's files app.js, manifest.js and vendor.js inside base.html (django template). I created a vuejs component named article-list in ArticleList.vue file. The problem is inside django's template, I am not being able to access this component. It is rather rendered as html tag inside template.

GraphQL on AWS lambda: The request could not be satisfied. How to solve 403 error?

SendGrid Django Template tags returning HTTP Error 400: Bad Request
Having an annoying issue. I am using Django to send data to sendGrid templates. But when I add substitutions I get a HTTP Error 400: Bad Request. If I dont add anything in the dictionary it works just fine emailing the template as expected.

inlineformset_factory choices not set correctly when using django-schemas
I have created an inlineformset_factory, but when I implement the Post method on my view the system mentioned that my inline form is not valid. After some debugging I found out that the choices that are in one of my inlineformset_factory fields are not accurate, this happens because I'm using django-schemas. for some reason when the inlineformset_factory is defined, it uses the public schemas and not the tenant schema, which makes the choices in my inlineformset_factory field incorrect. Note: The model that uses the inlineformset_factory has 2 Foreign Key 1 with the Configuration Object and the other with User, the issue occurs with the User. Here is the code that I have model.py class Configuration(Control): uuid = kp.ObjectIDField() name = kp.ObjectNameField() description = kp.ObjectDescriptionField() class ConfigurationMember(models.Model): uuid = kp.ObjectIDField() user = models.ForeignKey(User, on_delete=models.CASCADE) owner = models.BooleanField(default=False) configuration = models.ForeignKey(Configuration, on_delete=models.CASCADE) forms.py MemberFormSet = inlineformset_factory(Configuration, ConfigurationMember, fk_name='forecastConfiguration', fields=['user', 'owner'], can_delete=False, extra=3) View.py class ConfigurationCreateView(CreateView): model = Configuration form_class = ConfigurationCreateForm template_name = 'frontend/base/config_create.html' object = None # success_url = '' def get(self, request, *args, **kwargs): """ Handles GET requests and instantiates blank versions of the form and its inline formsets.

Django: Get the detail object inside Change_form template
from the Django change_form.html template. I would like to re-structure the default tabular display of the page. Its an invoice and I therefor need to render the page as invoice page. In order to do this I need the hold of the object storing the details for the page. If this was for change_list.html template, I could have accessed the object by iterating through cl.result_list like so {% for object in cl.result_list %} <tr> <td>{{ object.invoice_number }}</td> <td>{{ object.payment_type }}</td> <td>{{ object.billed_to }}</td> <td>{{ object.total_cost }}</td> <td>sup</td> </tr> {% endfor %} Similarly I want to access the obj in the change_form.html so that I can call the field name and get its value like object.invoice_number. Please any ideas on how to proceed? Thanks
