Django admin limit rights
In my Django project I have the models Project, Person, Task and Info. Thing is, however, that the Project is the parent model. Person, Task and Info belongs to the Project. If I add a Person, Task or Info I have to choose the Project (ForeignKey) it belongs to. My problem: Those projects are independent and I have different project managers. My goal is that in the admin interface the project manager of project A for example can only add a Person to HIS project, same with Info and Task. I don't want that the project manger of project A can see/edit/add/delete things of project B. Unfortunately, I could not find options in the Django admin that meets my requirements. If the project manager logs in he should only see instances that belongs to his project, nothing else. How would you solve that issue? -
Wagtail: accessing data models outside of an app
Very simple really. But I'm new to django and be extension wagtail too. I want to display the posts from an app on the homepage, or within any other django app for that matter. Current app structure: website/home/ website/blog/ website/portfolio/ Currently I can easily display the posts from 'web_development items' in a nice for loop on the 'web_development index page'. When I try to extend this to the homepage, nothing works. How do I access the models, etc of one app from another (in this case the 'home' app. Portfolio modelss.py: from __future__ import unicode_literals from django.db import models from django import forms, utils from wagtail.wagtailcore.models import Page from wagtail.wagtailcore.fields import RichTextField from wagtail.wagtailsnippets.models import register_snippet from wagtail.wagtailadmin.edit_handlers import FieldPanel, InlinePanel, MultiFieldPanel, PageChooserPanel from wagtail.wagtailimages.models import Image from wagtail.wagtailimages.edit_handlers import ImageChooserPanel from modelcluster.fields import ParentalKey, ParentalManyToManyField from modelcluster.tags import ClusterTaggableManager from taggit.models import TaggedItemBase, Tag as TaggitTag class PortfolioHome(Page): description = models.CharField(max_length=255, blank=True,) content_panels = Page.content_panels + [ FieldPanel('description', classname="full"), ] class PortfolioPage(Page): body = RichTextField(blank=True) feature_image = models.ForeignKey( 'wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, related_name='+' ) categories = ParentalManyToManyField('portfolio.PortfolioPageCategory', blank=True) tags = ClusterTaggableManager(through='portfolio.PortfolioPageTag', blank=True) pub_date = utils.timezone.now() content_panels = Page.content_panels + [ FieldPanel('body', classname="full"), FieldPanel('categories', widget=forms.CheckboxSelectMultiple), FieldPanel('tags'), ImageChooserPanel('feature_image'), ] Homepage models.py: … -
Passing string over urls django
I'm having trouble in understanding this error in my code, first let me try and explain what is happening and what I'm I trying to do. My code is designed to load up 45 separate text files into an array, including the weight of each word/phrase and the word phrase itself. This has to occur at the beginning, before any description is received. Second, once the description is received, it is parsed by my software into words/phrases, which are compared to the words/phrases in the array. Third, my software then provides the top three classes, in rank order (first/second/third) by number, along with the score for each class. I've made a django application that will serve this code, so I have a form which will provide two parameters classes and description, like this: class TrademarkClassifierForm(forms.Form): """ TODO: This forms will cover the questions the initial classifier program does :returns: TODO """ classes = forms.CharField(max_length=10, label="Test all trademark classes? Type 'yes' to do so or else enter the class to be tested ") description = forms.CharField(widget=forms.Textarea) def __init__(self, *args, **kwargs): super(TrademarkClassifierForm, self).__init__(*args, **kwargs) self.helper = FormHelper() self.helper.add_input(Submit('submit', 'Submit')) Then I want to pass this two parameters in the view over the … -

how to return user from django-rest-framework-social-oauth2 convert token view?
I am currently using Django-rest-framework-social-oauth2 and it's convert-toke endpoint.

RECEIVING email from Django website
I would like to enable people that visit my website to be able to send me an email to my yahoo mail. How can I do this? Now, I don't have a mail server (yet). Would it be necessary? The idea is for the person sending the email to fill in his email, subject and message, and then it would be posted to my yahoo email. def email(request): if request.method == 'GET': form = ContactForm() else: form = ContactForm(request.POST) if form.is_valid(): subject = request.POST.get['subject'] email = request.POST.get['email'] message = request.POST.get['message'] if subject and email and message: try: send_mail(subject, message, email, ['my_email@yahoo.com'], fail_silently=False,) except BadHeaderError: return HttpResponse('Invalid header found.') return redirect('thanks') else: return HttpResponse('Make sure to have all fields filled.') return render(request,"mywebsit/contact.html", {'form':form}) The form renders ok, but when I press send it acts as if it has sent the message, but when I open my yahoo mail there's nothing new there. I read it would be necessary to configure some things at settings.py, but, as far as I get it, it is meant to SEND, whereas what I want is to RECEIVE. Inspite of that, I tried configuring it, EMAIL_USE_TLS = True EMAIL_HOST = 'smtp.mail.yahoo.com' EMAIL_PORT = 465 EMAIL_HOST_USER = … -
Testing database in django other than django models
I am using mysql-server and MySQLdb for accessing my database. I have not even used django models to accessing the database tables. Now the problem comes while testing. All the django documentation is talking about the testing using django models. While testing a data, i have to insert data into the database using cursor.execute() function then i have to read from that. But this waste out my time. Also TestCase class run all database query in transaction and my doubt is that, this will be same for mysql-server and myqldb? I am using MySQLdb since it is faster than django models. Can anyone tell me how can i make the testing simpler ? How can i test the database in django? -
How do I update a form having select option in Flask (Python)
My question is about how to update select option in flask. I have created a registration form which contains select option to select Department. There are four options in department, the selected value is getting stored in MySQL database. This is working perfectly. Now I need update user page where user can update their details. The options are static and not fetching from database, only selected value is getting stored. Is it possible to get the form select option as pre-selected? <div class="input-group" style="margin-bottom: 5px;"> <label class="input-group-addon">Department:<span style="color: red">*</span> </label> <select name='employee_status' class="form-control"> <OPTION selected value='Sales'>Sales</OPTION> <OPTION value='Marketing'>Marketing</OPTION> <OPTION value='Support'>Support</OPTION> <OPTION value='Development'>Development</OPTION> </select> </div> Thanks in advance. -
Using Matplotlib with Django
I have built a simple web application using Django that reads a csv file and allows users to plot graphs by selecting X & Y attributes. The frontend makes use of AJAX calls to call backend methods to plot graphs using Python's Matplotlib. The issue arises when the plots are called asynchronously, causing a race condition: Different charts get plotted to the same figure. In attempts to overcome this problem, I assign random "id" to each user so that I can call matplotlib to get a figure number -- So each user plots on different figures. import matplotlib import pandas as pd matplotlib.use('agg') def plot_graph(id, args) fig = plt.figure(id) # This method plots a graph on 2 axes However, this does not solve the problem -- When a user plots 3 graphs at one time the graphs overlap on each other. -
Graphene Django without Django Model?
I've successfully used Graphene-Django to successfully build several GraphQL calls. In all of those cases I populated, in whole or in part, a Django model and then returned the records I populated. Now I have a situation where I'd like to return some data that I don't wish to store in the Django model. Is this possible to do with Graphene? Robert -
get_search_results : AssertionError Cannot reorder a query once a slice has been taken
In my Django Admin, i set a feature where the admin can search for products with certain category, so when i search "BreastPad", it will show products that have name of BreastPad, but if i search "category:Bra", it will look for products that have category of Bra. Now here is the problem, when the total of the products is bigger than the "list_per_page", i always get this error: AssertionError at /admin/ecoommerce/product/ Cannot reorder a query once a slice has been taken. For now i fixed the error simply by keep adding the list_per_page from 50 to 100, and now 200. I tried to simply just cut the total products to 50 by using all_products[:50] when the list_per_page is 50, but it still shows that "cannot reorder a query once a slice has been taken" exception. Please help. def get_search_results(self, request, queryset, search_term): # check if string contains the word category:XXXXXXXXXXXX if "category:" in search_term: # remove the word category: the_searched_category = search_term[9:] # search Product_category with that name the_searched_category = Product_TW.objects.all().filter(name=the_searched_category).first() if the_searched_category != None: all_products = Product_TW.objects.all().filter(product_categories__in=[the_searched_category]).distinct() return all_products, True else: return Product_TW.objects.none(), True else: queryset, use_distinct = super(Product_Admin, self).get_search_results(request, queryset, search_term) return queryset, use_distinct list_per_page = 100 -

Django class-based UpdateView
We are using Django 1.9.5. I am writing update company profile view. I want to have two fields on my update profile page: company name, apikey(generated with a dedicated function).

Django form saving all values to 0 when I change just one
I have gotten the application to look as I want on the screen but the form won't save correctly. The end goal is to have a dynamically generated table, with some td's being editable fields, based off of data in a few models. First my "Project" model gives a start date and end date for a project which is turned into start and end dates for each week. This is passed as the start and end date for the function in question. The function below takes those dates and generates values and form fields based on the associated objects in my "Allocation" model. This model contains records of each unique allocation: class Allocation(models.Model): user_id = models.ForeignKey(Resource) project_id = models.ForeignKey(Project) week = models.DateField(default=timezone.now) allocated_hours = models.IntegerField(default=0) actual_hours = models.IntegerField(default=0) The below function is displaying model fields with initial data for any user during a date range where they are allocated hours on a given project. It is also creating blank model fields for any where the user is not allocated and puts an initial value of 0. Everything looks fine on the page, but when I change a value and click save, all fields are saved in the db with 0. … -
Django + Postfix reset password email not beeing sent
I have set a django app in my cloud server and I'm trying to configure it to send password reset emails. First I configured my views and tested them with the django console e-mail backend EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' And it's working, I can see the e-mail sent to my console when I visit the password reset view. Next I configured postfix to be my backend. Postfix is working and I receive the e-mails I send with this command: echo "Body" | mail -s "Subject" myemail@gmail.com After this I changed my django settings.py to use postfix like this EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'localhost' EMAIL_PORT = 25 EMAIL_HOST_USER = '' EMAIL_HOST_PASSWORD = '' EMAIL_USE_TLS = False DEFAULT_FROM_EMAIL = 'Noreply <noreply@mydomain.com>' If I use python manage.py shell and run: from django.core.mail import send_mail send_mail('Subject', 'Body', 'noreply@mydomain.com', ['myemail@gmail.com'], fail_silently=False) I am also able to receive the e-mail. However when I go to my site password reset view I am not getting any e-mails sent! In journalctl -u postfix -xe I get the following messages: postfix/smtpd[23411]: connect from localhost[127.0.0.1] postfix/smtpd[23411]: 7BAED13D02E: client=localhost[127.0.0.1] postfix/cleanup[23414]: 7BAED13D02E: message-id=<20170820234125.23051.46440@mydomain.com> postfix/qmgr[20567]: 7BAED13D02E: from=<noreply@mydomain.com>, size=974, nrcpt=1 (queue active) postfix/smtpd[23411]: disconnect from localhost[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 postfix/smtp[23415]: connect … -
Whats the difference iterating over the queryset in these two ways?
I was using Django for building my project and came across these two ways. One way is : users = Users.objects.filter(is_verified=True) for user in users: print user.user.id And the second way is : users = Users.objects.filter(is_verified=True) for user in users: print user.id At first I thought the first way wont work but it was working and was quite slow then the second way. -
Django Web App Code works on local dev machine but not when deployed to server
I have a Django web project that i am working on which overall has gone pretty smoothly. I have a view below which grabs objects from the database and displays them via a template to the user. def index(request): all_occurrences = Occurrence.objects.all().order_by("-pk") calculate_percentage_right() context = { 'all_occurrences': all_occurrences, 'percentage_right': calculate_percentage_right() } query = request.GET.get("q") if query: all_occurrences = all_occurrences.filter( Q(Subject__icontains=query) | Q(Details__icontains=query)) return render(request, 'wrong/wrong_view.html', { 'all_occurrences': all_occurrences, }) else: return render(request, 'wrong/wrong_view.html', context) The issue that is occurring which to me makes no sense to me is that I am using a function to calculate a percentage right which is based on an object attribute called "timewrong". When I run this on my local machine it performs as expected, when I deploy this to my web server which is hosted on an Amazon EC2 Instance it does not calculate the percentage correctly. I either get 100% or 0% no in between. I have verified that on the webserver it is seeing all of the variables I have created correctly. The problems appears to occur when the division happens to get me to the percentage. def calculate_percentage_right(): wrongs = Occurrence.objects.all() total_minutes_wrong = 0 for wrong in wrongs: total_minutes_wrong += wrong.TimeWrong … -

Django: Restrict access to page
In my Django project I have Products. You can access products using this url pattern: example.com/tshirt or example.com/jacket etc. Moreover, you can view some other pages for those products, i.e.: example.com/tshirt/details or example.com/jacket/buy My problem: When I create a new product in my admin interface, the product is deactivated by default (I can activate it later). The reason is that when I create a new product I often don't have all necessary information yet (i.e. price). As long as a product is deactivated all URLs starting with example.com/this-one-product should not be visible for the normal visitor (getting 404 error). Unfortunately, I don't know how to do that. My goal is that it's visible for the super user or users from the staff. Because it makes sense that they can check that product and see how it looks like when it's rendered. But, as said, it should not be visible for the normal visitor of the webpage. Now I could of course create if statements in all those views (and check if superuser or from staff), but that does not sound like a elegant solution. Because I would have to add those statements to many different views and that's against DRY …
