Crispy form error with foreign-key, which I get from queryset.
This is an issue I am having while using Django crispy form. Following is the model field (showing only the necessary codes)" class Product(models.Model): name=models.CharField(max_length =200) unit = models.ForeignKey(Unit,related_name='product_master_master_unit') manufacturer=models.ForeignKey(Manufacturer,related_name='product_master_master_manufacturer') tenant=models.ForeignKey(Tenant,related_name='product_master_user_tenant') objects = TenantManager() Now, this is my form which I've used before using crispy-form. I've to query only those fields, which are specific to current tenant. That is done according to the following: class ProductForm(forms.ModelForm): def __init__(self,*args,**kwargs): self.tenant=kwargs.pop('tenant',None) super (ProductForm,self ).__init__(*args,**kwargs) # populates the post self.fields['unit'].queryset = Unit.objects.for_tenant(self.tenant).all() self.fields['manufacturer'].queryset = Manufacturer.objects.for_tenant(self.tenant).all() class Meta: model=Product exclude =('slug', 'tenant') This works fine if I don't use crispy form. However, on using crispy form the error I get is that the foreign-key field, related to Unit and Manufacturer (which are being queried for specific tenant) is not showing any option in the crispy form. Is there any way I can actually show that in crispy form, or do I have to abandon this crispy form altogether? Just for helping you out, I'm doing in my form what one could do with django's "ForeignKey.limit_choices_to" , if it allowed dynamic selection. Any help would be greatly appreciated. -

AttributeError: '__proxy__' object has no attribute 'regex'

Should I use geodjango over Django?
My goal: build a web application that provides map visualization of large data, entirely in Python. I have little experience in web frameworks, but I'm decent on the data side of things. I have seen a lot of rep for Django and it looks great. Geodjango seems promising, however my current backend is Apache Solr. I have seen haystack which supposedly provides the interface between geodjango and solr (I think). However when I looked at it, it seemed it was just building queries for me to relay to solr. I can do that just fine with other libraries. My question is, if I would like to manually handle my own Solr interface, is GeoDjango going to do anything for me that Django cant? I haven't started working on the application and want to make sure I know what my tools are going to do for me before hand. I'm open to suggestions as well as long as my constrains are met (Python/Solr). -

How to use SearchVector with multiple fields from a list of strings
I don't have a lot of Python experience and can't figure out how to use a list of strings with the SearchVector functionality described here. I'm using Django 1.10 with PostgreSQL 9.6 and have verified that this works if I write the fields in manually. This function is from a class based view and its purpose is to receive a string from a form, then do a full text search against all CharFields in all Models within MyApp, then return the results (planning on using itertools to combine multiple QuerySets once I get this working). I don't want to hardcode the fields because we will be adding new objects and new fields regularly - its a sort of corporate middleware app where I am not able to master the data. def get_queryset(self): searchTargets = defaultdict(list) myModels = (obj for obj in apps.get_models() if obj._meta.label.startswith('myapp') and not obj._meta.label == 'myapp.ConfigItem') for thing in myModels: fieldNames = (x.name for x in thing._meta.fields) for thisField in fieldNames: if thing._meta.get_field(thisField).get_internal_type() == 'CharField': searchTargets[thing._meta.object_name].append(thisField) user_query=self.request.GET['user_query'] for key in searchTargets.iterkeys(): targetClass=class_for_name('myapp.models',key) results = targetClass.objects.annotate( search=SearchVector(searchTargets[key]), ).filter(search=user_query) #only a single QuerySet will be returned. return results I've tried ','.join(MyList) but of course that just makes one big … -

(Django) page showing \u200e code. (PROVIDING GOOD INFO I've been stuck for a VERY long time)
Hey guys I am beyond frustrated/exhausted trying to fix this unicode code \u200e showing in my web page. I tried everything I can think of. Here is what my page looks like, its data scraped articles from news.google.com and shown on my page with the time submission (the time submission is where the \u200e pops up everywhere) http://i.imgur.com/lrqmvWG.jpg I am going to provide my views.py, my articles.html (the page in the picture that is set up to display everything), and header.html (for whatever reason. But this is the parent template of articles.html for the CSS inheriting). Also, I researched and know that the \u200e is a left-to-right mark and when I inspect the source in news.google.com, it pops up in the time submission element as &lrm; like so: <span class="al-attribution-timestamp">&lrm;51 minutes ago&lrm;</span> I tried editing the views.py to encode it using .encode(encoding='ascii','ignore') or utf-8 or iso-8859-8 but it still displays \u200e everywhere. I put it in so many different parts of my views.py too even right after the for loop (and right before it gets stored as data in the variable "b" and its just not going away. What do I need to do?
