Use NVL with string in Django?
On a Django app, I'm using cx_Oracle to display a roster of sports players: def get_players(self, sport_code='', term=0): """ :rtype: object """ con = cx_Oracle.Connection(settings.BANNER_CONNECTION_URL) cursor = con.cursor() query = 'select PREF_NAME, CLASS, ELIGIBLE_HOURS, CHECKED_IN, SEASONS_USED, MAJR1, NVL(MINR1, Null), CA_EMAIL, ID from swvsprt_web where ACTC = \'%s\' AND term = \'%s\' ORDER BY PREF_NAME' % ( sport_code, term) cursor.execute(query) players = cursor.fetchall() cursor.close() con.close() return players I want minor to just be blank if they don't have a minor NVL(MINR1, Null) But I can't quite get NVL to behave. "Null" makes it print the word "None." If I do NVL(MINR1, 0) it will display a 0, but if I try any of the following, they crash the site with a 500 error: NVL(MINR1, ) NVL(MINR1, '') NVL(MINR1, "") Can we use NVL to make it show null values as just nothing? -
AttributeError: 'module' object has no attribute 'PROTOCOL_TLSv1_2' with Python 2.7.6 on Ubuntu
I am having an issue that is eerily similar to this post on SO. I cannot use the answer there because I am on Ubuntu, and brew is for Mac. When I try to launch my Django server, (python manage.py runsslserver) I get the following error: AttributeError: 'module' object has no attribute 'PROTOCOL_TLSv1_2' I know I have OpenSSL installed for Python, as when I run import ssl and then print ssl.OPENSSL_VERSION in my Python environment, I get: OpenSSL 1.0.1f 6 Jan 2014 There must be something really simple I am missing here. Any help at all is appreciated. -
Translate country names to match browser language preference
I want Azerbaijan to show up in the browser as as Azerbaïdjan (French spelling). 1) I placed the django_countries dir (downloaded from https://pypi.python.org/pypi/django-countries) in my project root. 2) added "django_countries" to my INSTALLED_APPS 3) added "from django.utils.translation import ugettext_lazy as _ " in my app1/forms.py 4) changed the following (in the forms.ModelForm subclass): def clean_name(self): return self.cleaned_data['name'] to: def clean_name(self): return _(self.cleaned_data['name']) 5) changed the language preference in Chrome to French What am I missing?

Cannot get the same digest (sha256) from same POST data
I am using Python requests package to send JSON data to an API. If the same data has been sent before the API discards it. The test uses a SHA256 digest of he data for comparison. Ideally I would obtain the digest in the server, but the digest keeps changing for the same data in different POST request. Now I do the hash in the client and send it with the data, but THERE MUST be a way to get constant data server side when the client POST the same JSON. The django request.body is bytes and unsuitable for hashing, it must be converted first to UTF-8, but even doing that leads to a different hash each time. Ideas? Thanks. -

django select widget works painfully slowly, but only on one project
I have a simple form and view that operate a universal Django object: from django.contrib.sessions.models import Session class TestForm(forms.Form): sessions = forms.ModelChoiceField(queryset=Session.objects.all()[:100]) class TestFormView(TemplateView): template_name = 'test_template.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['form'] = TestForm() return context And I render the field in a template simply like so: {{ form.sessions }} This very query behaves very differently in my different projects. It renders within a second on all of the projects except one, where it takes 30 seconds(!) to render. At the same time, if I create a <select> element explicitly everything renders fast again: <select> {% for s in form.fields.sessions.queryset.all %} <option value="{{ s.id }}">{{ s }}</option> {% endfor %} </select> I tried rendering Select widgets for other objects in the projects, and the result is the same: the {{ form.field }} syntax hangs the server if there are over 100 objects, and the explicit iteration works fast. So this project has an issue with Django widgets. What is even more weird is that the bug disappears when deployed to Heroku on the same Postgres version (9.6), same Python (3.5.0) and Django (1.11) versions. I tried completely reinstalling Virtualenv and all the modules from the requirements - this … -
When saving modelform, how to give a parent to the child?
In my model, the class Child(Parent) is inheriting the class Parent(models.Model). I've got a ChildForm(forms.Modelform) based on the Child model which allows to get some data from a form. then: if request.method == 'POST': # the form has been posted myform = ChildForm(request.POST) if myform.is_valid(): thechild = myform.save(commit=False) thechild.fieldA = A ... # adding some additional data to the object thechild.save() myform.save_m2m() # because there's an additional M2M table link to the Child. The question is: The parent already exists. I want to create a Child based on the parent (in a One to One relationship). How do I pass the Parent to the Child in the way that it knows who is its parent? -
Django Crispy Forms Add New Empty Form to ModelFormSet
What is the crispiest way to add a new, empty form to a modelformset with existing forms? forms.py: class MyForm(ModelForm): class Meta: model = MyModel fields = '__all__' MyFormSet = modelformset_factory(MyModel, extra=1, exclude=(), form=MyForm) class MyFormsetHelper(FormHelper): def __init__(self, *args, **kwargs): super(MyFormsetHelper, self).__init__(*args, **kwargs) self.form_method = 'post' self.template = 'bootstrap/table_inline_formset.html' self.add_input(Submit("submit", "Save")) template: {% extends "base.html" %} {% load staticfiles %} {% load crispy_forms_tags %} {% block stylesheets %} {{ block.super }} {% endblock stylesheets %} {% block content %} {% crispy formset helper %} {% endblock content %} I see that crispy forms has a way to add a generic button, but I don't see how to tie that to an action. I also don't know how crispy forms would create an empty form. Prior to discovering crispy forms, I was writing out all the template code and used something like the below to render the empty form. <div id="empty_form" style="display:none"> <table class='no_error'> <tr> <td>{{ modelformset.empty_form.Field1 }}</td> <td>{{ modelformset.empty_form.Field2 }}</td> <td>{{ modelformset.empty_form.Field3 }}</td> </tr> </table> </div> <input type="button" value="Add" id="add_more"> Thank you for any insight you all might have. -

Passing a python's script object to Django's views.py
I'm trying to learn how to transfer my Highchart from a python script on to Django. I've been using this solution thread to get there (but in vain so far). I've got a python script called script.py that returns an object named chart_data. Now in Django, I'd like a function in my views.py to execute that script.py file, grab the chart_data object and allocate it to a new object called 'data'. My script.py file is stored in a directory called /scripts/ in my project root directory, and it contains its own __init__.py file. With the code below the server returns an error that states: global name 'chart_data' is not defined. Any explanations as to what I'm doing wrong here would be greatly appreciated. ### views.py from __future__ import unicode_literals import datetime import subprocess import scripts def plot(request, chartID = 'chart_ID', chart_type = 'line', chart_height = 500): raw = subprocess.Popen('~/scripts/script.py', shell=True) data = chart_data chart = {"renderTo": chartID, "type": chart_type, "height": chart_height,} title = {"text": 'my title here'} xAxis = {"title": {"text": 'xAxis name here'}, "categories": data['Freq_MHz']} yAxis = {"title": {"text": 'yAxis name here'}} series = [ {"name": 'series name here', "data": data['series name here']}, ] return render(request, '/chart.html', {'chartID': chartID, … -

django-allauth twitch redirect_mismatch and a 404 page not found
I've been working the past 2 days on getting Twitch to be the sole social account for the website I'm building. I have ran into snags here and there though I've been able to find answers on google and on here. Sadly I have hit the limit and need to as as the Twitch setup seems not to be common and other than being told to go where to get an app key there isn't much documentation to be found. I'm able to get to the login page with the button clickable. My issue is the redirect_mismatch error. Inside setting up the Twitch clientid and secret key inside the admin panel there was no place to set a redirect url. After some digging I could the following: http://myapp.herokuapp.com/accounts/twitch/callback/ So naturally I went back into my twitch dev account and set the call back url. Waited for about 6 hours as I had other things to get done. Came back and twitch is still giving me the redirect_mismatch. Is there a different link for Twitch to use with django-allauth for their callback url? Lastly when I do get the information back from twitch stating its a wrong url redirect... ?error=redirect_mismatch&error_description=Parameter+redirect_uri+does+not+match+registered+URI&state=mhzOola6Em1m The … -

Getting forms to display in HTML with Django
so I've gotten forms to display correctly before, I'm just a little lost as to why I am using certain words when doing so, and I'm wondering why I've used different words to get different forms to display. In this first example (colorist_form.html) I am using {{ form }} which does get the form to display {% extends "base.html" %} {% block content %} <div class="colorset-base"> <h2>Create new post</h2> <p class="hint">Add hex codes for each color you would like to include.</p> <form id="postForm" action="{% url 'colorsets:new_color' %}" method="POST"> {% csrf_token %} {{ form }} <button type="submit" class="submit btn btn-primary btn-large">Add Color Set</button> </form> </div> {% endblock %} However, in this example (widget_form.html) I am using the same {{ form }} but now the form does not display {% block content %} <div class="colorset-base"> <h2>Create new widget</h2> <form id="postForm" action="{% url 'adminpanel:create-widget' %}" method="POST"> {% csrf_token %} {{ form }} <button type="submit" class="submit btn btn-primary btn-large">Add Widget</button> </form> </div> {% endblock %} Also in my register.html I am using {{ user_form }} which does get the form to display. {% extends "base.html" %} {% block content %} <div class="form-base"> {% if registered %} <h1>Thank you for registering!</h1> {% else %} <h2>Register</h2> … -

Python List Bug in a for loop
