Upgrading Python in Django cartridge in Openshift to install Quantlib-Python
I am using the Django cartridge in Openshift. This cartridge has Python version 3.3.2. Is there a way to upgrade the python to 3.6? I am trying pip install QuantLib-Python in ssh console. It gives me the following error: Collecting QuantLib-Python Could not find a version that satisfies the requirement QuantLib-Python (from versions: ) No matching distribution found for QuantLib-Python. I did the same install in my Windows machine which has a Python version 3.6. Hence I feel that I will be able to my pip install if I upgrade the python. I would appreciate any suggestion. Thanks. -

issue cycling through forms with different names in django views
I am working on a project and i am having an issue with djago form templates and it only returning one part of the form. So what is happening is: I have a ModelForm that contains two fields which are amount and description. Within the view I cycle through a list of users. for every user in the loop it creates a form with the users username prefix and then passes the list of forms into the html template. The issue that i am having is that all of the forms and their prefixes are passing to the html tempalte, but when it is submitted, only the last form is passed back to be proccessed. I have an example below and the file info that is related to this issue. Here are the passed in forms that were created in the view before html template is displayed: omarform <tr><th><label for="id_omar-amount">Amount:</label></th><td><input id="id_omar-amount" name="omar-amount" step="0.01" type="number" value="0.0" /></td></tr> <tr><th><label for="id_omar-description">Description:</label></th><td><input id="id_omar-description" maxlength="250" name="omar-description" type="text" /></td></tr> haniform <tr><th><label for="id_hani-amount">Amount:</label></th><td><input id="id_hani-amount" name="hani-amount" step="0.01" type="number" value="0.0" /></td></tr> <tr><th><label for="id_hani-description">Description:</label></th><td><input id="id_hani-description" maxlength="250" name="hani-description" type="text" /></td></tr> ranaform <tr><th><label for="id_rana-amount">Amount:</label></th><td><input id="id_rana-amount" name="rana-amount" step="0.01" type="number" value="0.0" /></td></tr> <tr><th><label for="id_rana-description">Description:</label></th><td><input id="id_rana-description" maxlength="250" name="rana-description" type="text" /></td></tr> Here is what is displayed … -

Django Model self referencing M2M field
I'm trying to get a Django model to automatically construct a typical __str__(self) value for itself (in the model definition), but based on 3 ManyToMany Fields. Unlike when using basic field types (as in the first two models), this doesn't appear to work for M2M fields (see the third model). The model migrates fine, but causes errors when being referenced in the admin. Any help much appreciated, thanks! class Party(models.Model): name=models.CharField("Party", max_length=150) def __str__(self): # __unicode__ on Python 2 return self.name class Meta: ordering = ('name',) class ValCharBehav(models.Model): name=models.CharField("Value / Character / Behaviour", max_length=150, unique=True) def __str__(self): # __unicode__ on Python 2 return self.name class ValCharBehavWithPeople(models.Model): vcb=models.ManyToManyField(ValCharBehav, verbose_name="Value / Character / Behvaiour") bywhom=models.ManyToManyField(Party, verbose_name="By Whom", blank=True, related_name="valCharByWhomReverseAccessor") towhom=models.ManyToManyField(Party, verbose_name="To Whom", blank=True, related_name="valCharToWhomReverseAccessor") def __str__(self): # __unicode__ on Python 2 return self.vcb.name+": by: "+self.bywhom.name+", to: "+self.towhom.name -

Query to retrieve neighbors is too slow
I have a set of ORM models representing a directed graph, and I'm trying to retrieve all the adjacent nodes to a given nodes ignoring edge direction: class Vertex(models.Model): pass class Edge(models.Model): orig = models.ForeignKey(Vertex, related_name='%(class)s_orig', null=True, blank=True) dest = models.ForeignKey(Vertex, related_name='%(class)s_dest', null=True, blank=True) # ... other data about this edge ... The query Vertex.objects.filter(Q(edge_orig__dest=v) | Q(edge_dest__orig=v)).distinct() returns the correct result, but in my case it takes far too long to execute. Typically for my application there will be around 50-100 vertices at any given time, and around a million edges. Even reducing it to only 20 vertices and 100000 edges, that query takes about a minute and a half to execute: for i in range(20): Vertex().save() vxs = list(Vertex.objects.all()) for i in tqdm.tqdm(range(100000)): Edge(orig = random.sample(vxs,1)[0], dest = random.sample(vxs,1)[0]).save() v = vxs[0] def f1(): return list( Vertex.objects.filter( Q(edge_orig__dest=v) | Q(edge_dest__orig=v)).distinct() ) t1 = timeit.Timer(f1) print( t1.timeit(number=1) ) # 84.21138522100227 On the other hand, if I split the query up into two pieces I can get the exact same result in only a handful of milliseconds: def f2(): q1 = Vertex.objects.filter(edge_orig__dest=v).distinct() q2 = Vertex.objects.filter(edge_dest__orig=v).distinct() return list( {x for x in itertools.chain(q1, q2)} ) t2 = timeit.Timer(f2) print( t2.timeit(number=100)/100 ) # … -

Passing from django formset to
This is my first Django project and this little bit turned out to be quite hard. I am making an itinerary generator by using formsets. These can be duplicated (I already know at least how to do it by working out the management form and all). For every event (it's someone traveling) I have passed information about the starting date and ending date, which is displayed on the form like this: Date 1 [Form 1][Form 2], Date 2 [Form 3][Form 4]. My problem is that in the end, when I put it back into the view, I would like to use json.dumps to turn it into an array, with the idea that the code is more readable and usable. Something like this: { "28-June-2017": [ {"time": "8:00", "Breakfast": "b", "responsible": "Person1"}, {"time": "18:00", "activity": "Dinner", "responsible": "Person1"} ], "29-June-2017": [ {"time": "8:00", "activity": "Breakfast", "responsible": "Person2"}, {"time": "12:00", "activity": "Lunch", "responsible": "Person"} ] } Now, I have solved everything but this so far. I have thought of passing the variable to the template and generate an input where the date can be added for each formset (thus repeating data for every input) and then doing something on the view in … -
Issue setting specific modelform field's name django

I have a ModelForm that asks a user for an amount and description based on a model. Within the template file, I want to loop through objects saved in the database and for each of the users, I want the form to be displayed and change the inputs name to add the username in the input name: default now = amount(decimalField) and description(charfield) desired = usernameamounta combination of cycled username and amount and usernamedescriptiona combinationn of cycled username and description this makes it so that within the view, I can cycle through the same username list and get the correct field name by doing the same process as i did when changing the field input name...

How to test your django model using shell

I have coded my Django model as: class Work(models.Model): STATES = ( ('STARTED', 'started'), ('IN_PROGRESS', 'running'), ('FINISHED', 'completed'), ('ERROR', 'Error'), ) owner = models.ForeignKey("auth.User") temp = models.CharField(max_length=50, null=True, blank=True) current_run = models.CharField(max_length=50, null=True, blank=True) completion_percentage = models.IntegerField(blank=True, null=True) status = models.CharField(choices=STATES, max_length=50, blank=True, null=True) I have regenerated the db and now I want to use it Django views. But, before that is there a way to test it using python manage.py shell? I am trying to do: d_ = Work.objects.create(owner='admin') I get the error ValueError: Cannot assign "'admin'": "Work.owner" must be a "User" instance. Currently, I have userid as 'admin' in Users. I have tried doing few things to get around the error but I keep getting some kind of error because of the owner field (which is set to foreign key of auth.User). Any help will be appreciated here. Thank you! -
User Provided CSV in Django Web Project
I'm using Django to host a web application, and I would like to obtain a CSV file from the user, and process this information (using Python). I am currently using this line of code in the HTML to obtain the CSV file: <input type="file" accept="text/csv" id="mycsv"> Where in the Django project should I obtain the information from the CSV file, and how would I go about doing this? (I know the question is broad and doesn't give context for my specific project, but I figure that once I know how to access the data in the CSV I can figure the rest out). -
Dynamically structuring models django
I'm pondering a structure for an example that I am constructing and cannot figure out the optimal model structure. Basically I have a HTML canvas that I am building dynamically from a model. The current structure I have a Template and an Element model. Template contains a background image for the canvas and the Element model will have a ForeignKey back to the Template model. Element currently could be either a text Element or an image Element it also contains the x,y positions of the Element in the canvas I want to be able to dynamically create different canvases (at different urls) based on information that will be provided without having to continually create more Element instances. It seems to me there should be a third model involved here but what relationship is optimal? -
Translating formatted strings in Django not working
I have problem with translating formatted strings in Django using django.utils.translations. Only strings without format (%s or {}) are working. My locale/en/LC_MESSAGES/django.po file: msgid "foo" msgstr "bar" #, python-format msgid "foo %s" msgstr "bar %s" #, python-format msgid "foo %(baz)s" msgstr "bar %(baz)s " #, python-brace-format msgid "foo {}" msgstr "bar {}" #, python-brace-format msgid "foo {baz}" msgstr "bar {baz}" First string is working: >>> from django.utils import translation >>> translation.activate('en') >>> translation.ugettext('foo') 'bar' But rest is not: >>> translation.ugettext('foo %s' % 'bax') 'foo bax' >>> translation.ugettext('foo %(baz)s' % {'baz': 'bax'}) 'foo bax' >>> translation.ugettext('foo {}'.format('bax')) 'foo bax' >>> translation.ugettext('foo {baz}'.format(baz='bax')) 'foo bax' No mater if I use ugettext_lazy, gettext or gettext_lazy - same story, not translated output. Any idea why formatted strings are not working? Django 1.11.3 Python 3.5.3 -
