Getting an Ebay OAuth Token
I've been working on the ebaySDK for most of the week. I've managed to integrate the Trading and Shopping APIs into my project. For the trading API, I was using an Auth n Auth token which has a validity of upto 18 months. The OAuth Token which I need for the Sell APIs is valid only for a day, so I'll need to fetch it regularly before it expires. I followed the documentation on the site and even tried looking through python repos on github but I haven't been able to move forward as of yet. Here's a quick snippet of my request code, What am I doing wrong? import requests, json, base64, xmltodict AppSettings = { 'app_id' : 'my_app_id', 'app_secret' : 'my_app_secret', 'dev_id': 'my_dev_id', 'ruName': 'the_ruName_for_my_app' } authHeaderData = AppSettings['app_id']+':'+AppSettings['app_secret'] encodedAuthHeader = base64.b64encode(authHeaderData) session = requests.Session() print encodedAuthHeader url = 'https://api.ebay.com/identity/v1/oauth2/token' session.headers.update({ 'Content-Type':'application/x-www-form-urlencoded', 'Authorization':'Basic '+encodedAuthHeader }) data = { 'grant_type':'client_credentials', 'redirect_uri': AppSettings['ruName'], 'scope':'https://api.ebay.com/oauth/api_scope' } response = session.post(url, data=data).json() print response The response I'm getting is: {u'error_description': u'client authentication failed', u'error': u'invalid_client'} I checked all the keys. I even tried to get the token via the production signin provided by ebay but to no avail. The response I got from … -
Django inconsistency of uwsgi and dev servers
I faced strange problem. With the same Django project, site behaviour is different on development server and uwsgi server. Uwsgi and devsrv point to the same settings.py file. The issue here is that one particular app (commented out in settings file) is present in uwsgi server, but absent in development server. This app should be turned off on both servers. Files are the same, because it is the same tree. I have no idea where to seek for bug. It seems like uwsgi do not notice any changes in settings file, and stores previous version somewhere. I do restart uwsgi every time I make changes. I also tried rebooting machine. -
List of zipcodes within distance to user zipcode (Django Project)
Problem/desired Feature: If the user enters his zipcode together with an arbitrary radius/distance i want to return a list of zipcodes who are within the circle or partialy "cut" by the circle around the user location. Boundaries: I dont mind a couple of miles of uncertanties and or using third party apis Technology: Django with PostgreSQL I thought this might be a problem solved a lot so is there a API which i can implement in my Django app to accomplish this? I figured GeoDjango but it looks pretty heavyweight and requires a restructuring of my entire project. Right now i have a GeoPostalcode model as follows: class GeoPostalcode(models.Model): geoP_PLZ = models.CharField(max_length=50, default='') geoP_City = models.CharField(max_length=500, default='') geoP_Bundesland = models.CharField(max_length=400, blank = True, null = True) geoP_Land = models.CharField(max_length=300, blank = True, null = True) I have the data for my country and i think i would be able to get lat/lon as well. But i would prefer a solution using thrid party api(Google?) where i send a zipcode and radius and get a list of zipcodes back to do what ever i want with them. Anyone out there who solved something like this already and know good solutions/apis? Here … -

I am not able to use indexing on Django model field which contains large amount of text. I am using MySQL. What should I do?
First I was using models.TextField, but it doesn't support indexing. Switching to models.CharField didn't help as text size was greater than 50000 characters in some rows. Indexing is allowed for maximum 3072 bytes data in MySQL. Should I switch to another RDBMS or use NoSQL like MongoDB? I also tried to use haystack with whoosh for indexing and searching, but searching was very slow. -

Django class based views gueryset model isn't defined
I am producing a web app in Django that stores and sorts courses. The issue I am having is that the query set is not recognizing the model. I have managed to pull all in a class based view and mess around with the data, however, when I try and do a query set it simply says that the model "Course" is not defined.

send a signal which will unfollow comment thread Django
I have an comment section in my application, and I'm using this django-contrib-comment library. When someone post a comment it will automatically send a signal and mail will be send, so you will be notify when someone leave a comment. Now the idea is to have a list of Users in my model, like this comment_thread=models.ManyToManyField(User), so I can check for that list and if that user is on the list he will be able to unfollow this comment thread, so list will be check before sending mail, but this needs to be done only if he checkbox the button in the template. My question is how can I connect a button to this signal, can someone explain me please? This is my current signal: @receiver(post_save, sender=EmailAddress) def handle_email_address_save(sender, instance, created, update_fields, **kwargs): confirm = account_settings.ACCOUNT_EMAIL_CONFIRMATION_EMAIL must_confirm = instance.must_confirm if hasattr(instance, 'must_confirm') else False warning("handle_email_address_save called for email " + str(instance.email) + ", created = " + str(created) + ", confirm = " + str(confirm) + ", must_confirm = " + str(must_confirm)) if confirm and not instance.verified and must_confirm: instance.send_confirmation() warning("handle_email_address_save sent confirmation") # TODO: move to signals.py in quotes module @receiver(comment_was_posted) def handle_comment_posted(sender, comment, request, **kwargs): if comment.content_type.model == … -
Passing a python list and display correctly
I am trying to pass a list from a csv and fill a select menu in html using django. The format of my csv is like that ["otis","Otis"],["bel","Bel"]..

Django won't save ManyToMany field on ModelForm
I've got a model similar to the following (this is a condensed version of a long form): class UserProfile(models.Model): display_name = models.CharField() nationality = models.ForeignKey(Nationality) religion = models.ForeignKey(Religion) partner_nationality = models.ManyToManyField( Nationality, related_name='partner_nationality', blank=True) partner_religion = models.ManyToManyField( Religion, related_name='partner_religion', blank=True) And the following model form: class UserProfilePartnerPreferencesForm(ModelForm): partner_nationality = ModelChoiceField( queryset=Nationality.objects.order_by('name'), widget=CheckboxSelectMultiple, empty_label=None, required=False, to_field_name='id') class Meta: model = UserProfile fields = [ 'partner_religion', 'partner_nationality', ] widgets = { 'partner_religion': CheckboxSelectMultiple(), } So what I'm doing in the model form is: Not displaying some fields (the display_name) Changing the widget on a field Creating a custom queryset and changing the widget on a field. This form displays OK but the field where I've passed a custom queryset won't save. If I don't give any values for it, django complains with 'NoneType' object is not iterable while trying to save the field (partner_nationality in this example). If I give it a valid value, it says that the value isn't valid. So it seems like fields where I supply a custom queryset aren't being applied correctly when the form is saved. If I comment out the customisation (i.e. partner_nationality in the ModelForm), it saves correctly with the default settings. How can I … -
Run python function using custom button in Django admin

Now it maps to admin:index but I would like it to run printer function and go to another view (or show alert message using jquery - I will think about it). Printer function is just an example - in real it will do some database search/modify database and go to result view. -
Python dependency issues with Django on Docker
Im new to Docker and im having troubles porting my already existing and working Django project to Docker and im pretty much stuck right now since the issue is with the dependencies in my requirements.txt that are frozen and actually are working on my other environmets (Live on VPS with Ubuntu and Dev on a VM with Arch). The issue itself is while migrating the DB with djangocms_text_ckeditor/html5lib and was reported under eg. https://github.com/divio/djangocms-text-ckeditor/issues/336. How is the Docker environment different so that this error can occur on the same Base OS with the same Python- and dependency versions? what i tried so far: latest dependency versions (unfreeze) different package versions as mentioned on the issue reports. different python versions 3.4 - 3.6 (standart and alpine)(live runs on 3.5 standart) different base image (ubuntu 16.04 - 16.06) deleting package and package dependencies (leads to migration inconsistency) The dependency versions of my requirements file: djangocms-text-ckeditor==3.0.1 html5lib==0.9999999 Any ideas how to fix this issue? -
