How to display data from two different models on the same HTML page
I have two tables one called called PlayerLkup, which contains info about the player and serves as a lookup table. I have another table (called BattingStats) which contains a player's stats (and the playerid). The BattingStats table is a one-to-many (playerid is listed multiple times, one time for each season they played). My data from PlayerLkup is displaying fine, and it is using the playerid in the URL address to retreive a specific player. My question is how do I use the data from my BattingStats model/table onto that same page? I'm assuming my views page is where the work needs to be done. Is there a way to have multiple models passed into one view? I've tried same url, different views. It didnt seem to work for me. What do I need to do? Any help here would be appreciated. I posted this question before (and have since deleted it) but someone mistakenly tagged it as a duplicate so it didn't receive any attention. models.py class BattingStats(models.Model): playerid = models.CharField(db_column='playerID', max_length=9) year = models.IntegerField(db_column='Year', blank=True, null=True) g = models.IntegerField(db_column='G', blank=True, null=True) ab = models.IntegerField(db_column='AB', blank=True, null=True) r = models.IntegerField(db_column='R', blank=True, null=True) hr = models.IntegerField(db_column='HR', blank=True, null=True) rbi = models.IntegerField(db_column='RBI', … -

Running annotate or aggreagate on related objects and rendering in template?
I'm trying to do math/find the max/avg,etc. in my views and then render them in the template, but I can't seem to figure out how to get it to all work. The calculations need to be done over related objects and I feel like I've tried everything. At my wits end. views.py def program_detail_view(request, primary_key): survey = Survey.objects.get(pk=primary_key) maxResp = survey.objects.annotate(max_resp=Max('responseRelevance')) context = {'survey' : survey, 'maxResp': maxResp} return render(request, 'relevance/programStats.html', context=context) models.py class Survey(models.Model): ... class Choice(models.Model): survey = models.ForeignKey(Survey, on_delete=models.CASCADE) creationDate = models.DateTimeField(auto_now_add=True) pce = models.IntegerField( validators=[MaxValueValidator(4), MinValueValidator(1)], choices=radioChoices, ) interest = models.IntegerField( validators=[MaxValueValidator(4), MinValueValidator(1)], choices=radioChoices, ) responseRelevance = models.IntegerField(blank=True) template.html <li>Overall Relevance Score: {{ maxResp }}</li> I expect that the views will output the maximum response from the set of choices, but instead nothing shows up in the template no matter how I try to call it. I've tried the same for average and other annotate/aggregate functions. -
use of related manager with proxy models in Django
I have the following model structure: class Abstract_model(models.Model) # “Abstract model”, used to generate following 2 models. Abstract in this case is just a name foreignkey1 = models.ForeignKey("Proxy_model_1") foreignkey2 = models.ForeignKey("Just_a_Model") class Proxy_model_1(Abstract_model) # proxy model 1( main) class Meta: proxy = True class Proxy_model_2(Abstract_model)# proxy model 2(secondary) class Meta: proxy = True class Just_a_Model((models.Model) # The model. Main one... There are 1 base “abstract” model and 2 proxy models, inherited from the base model. Proxy_model_2 has many-to-one relationship to Proxy_model_1.

How to make existing model objects read-only but also be able to create a new one, using StackedInline class?
I have two models named 'Message' and 'Ticket'. Message has a Foreignkey to Ticket. I showed Messages of a Ticket in django admin, using StackedInline. But the problem is I want that the already created messages be read-only, while being able to create new message, too. I've also check bunch of questions; like this or this. But none of the was helpful!

How to see Django errors using NGINX and gunicorn
I have developed a Django app locally, and I am used to seeing the error messages on the webpage when things aren't correct with my programming. I have now moved this app over to digital ocean servers, using Ubuntu, NGINX, and gunicorn. Now when I have a problem in my Django code someplace, I get served very basic error messages from NGINX (or gunicorn?) on the webpage. Is there a method to see the full error log (like when the django app is being served on the local test server)? Or anyway to see more advanced error logs? DEBUG is set to True. -
