Connecting Django to an sensor using sockets?

Posted on April 24, 2014 at 10:46 PM by Stack Overflow RSS

I have a sensor that is connected to a GSM/GPRS module. The data is to be stored and displayed online with django. I want to also be able to send commands to the device. I'm unclear on how to connect the two parts of this project. As I understand it, sockets are not directly supported in django. I've taken a look a few libraries and other projects that use sockets in django, but I found them confusing and I am unsure as how to set up my project to use them (I'm new to django). My question: Is there an easier or better way of doing this without using sockets in django? For instance,a separate python socketserver...would that be able somehow relay the sensor data / commands back and forth? Thanks for your time.

Django/python: Model relationships for API related data

Posted on April 24, 2014 at 10:18 PM by Stack Overflow RSS

I am building a wrapper around an API, and as such I want to hold information that the API itself holds (I want any updated api information to be held on my server as well). This being the case, I need to build models that anticipate the data I will be receiving. So I started building these models. Let us assume they look like this: class ModelForAPI(models.model): #model fields here Now this data is going to steadily be collected and updated accordingly when it is needed to. Let's then assume that in addition to the models ive built to hold the api data, I have more data that is related but that is relevant on my server only. The question becomes: how is the best way to "extend" this data? I feel that there a few possible options, either I extend the api model like such: class Model(models.Model): api_information = ForeignKey(ModelForAPI) Or I subclass it like such: class Model(ModelForAPI): #model fields here Since I am dealing with API information that is going to be updated frequently with new information, I am not sure which would make my life easier in terms of model architecture. Any pointers would be much appreciated.

Django - How to create form fields by iterating through a database query?

Posted on April 24, 2014 at 10:14 PM by Stack Overflow RSS

So I would like to set up a form based on the values I have stored in my database. Let's say I have a model like this: class Questions(models.Model): question = models.CharField(max_length=350) And I would like to create a form in this way: for x in Questions: answer = forms.CharField(label = x.question) And thereby having exactly the number of answer fields in the form as there are questions stored in the database. Any ideas?

How to fix this database schema to avoid inconsistency?

Posted on April 24, 2014 at 10:13 PM by Stack Overflow RSS

I'm stuck on an issue of database design. How do I set this up to avoid problems with consistent data down the road? Let's consider three objects: (django model definitions below) TaskType TaskGroup foreignkey to TaskType TrainingTask foreignkey to TaskType foreignkey to TaskGroup The problem (at least I think this is a problem) is that if I have a TrainingTask, then it could potentially have inconsistent values for TaskType (via the direct foreign key and indirectly via the fk to TaskGroup). And some "facts" about these objects: TaskTypes hold meta information about TrainingTasks. TaskGroups are for grouping tasks of the same type. Elsewhere in my application I want to be able to take a TaskGroup and say "give me a random TrainingTask from this TaskGroup". There can be lots of TrainingTasks for a TaskType. All the TrainingTasks in a group should have the same type There can be lots of TaskGroups for a TaskType TrainingTasks with the same TrainingType can be in different TaskGroups Also, I am doing all this in Django, and TrainingTask is a subclass of Task (using Multi Table Inheritance), and thus TrainingTask inherits the fk to TaskType from Task. I would like to keep this structure ...

How to make a form that creates a new object and objects related by foreign keys in one request?

Posted on April 24, 2014 at 10:04 PM by Stack Overflow RSS

I have a Recipe model and a Step model, where multiple steps are linked to a recipe via a foreign key. What is the best solution for making a form that creates a new recipe and multiple steps at the same time? After googling around I have only found inline formsets, but they require an instance of the recipe (found by pk) but of course in practice the recipe would not be saved before the form is generated since they (the recipe and its steps) are created in one request. Anyone solved a problem similar to this?

Django messaging framework messages not making it passed the redirect()

I have some "save" code that sets a success message using the Django messaging framework upon successful creation of a record, then does a redirect back to the main 'application_update' view.

Django Rest Framework: Non-model service

Django, template attribute unique

Posted on April 24, 2014 at 7:39 PM by Stack Overflow RSS

I'm trying to implement a list of events to a js calendar. So the data for the calendar are like this: var studyEvents = { '04-03-2014' : '<span class="event">Event 1</span>', '05-08-2014' : '<span class="event">Event 2</span>', '12-09-2014' : '<span class="event">Event 3</span>' }; In case the are more than one events on the same day, the data are like this: var studyEvents = { '04-03-2014' : '<span class="event">Event 1</span>', '05-08-2014' : '<span class="event">Event 2-1</span><span class="event">Event 2-2</span>', '12-09-2014' : '<span class="event">Event 3</span>' }; So what I'm doing is getting a list with all events ordered by date. I want to check if there are more than one events in on the same day. I'm thinking that I could check(since the list is ordered by date) if the is not unique then there could be a way to put it on the same line. var studyEvents = { {% for event in events %} '{{|date:"m-d-Y" }}' : '<span class="event">{{ event.title }}</span>'{% if not forloop.last %},{% endif %} {% endfor %} }; I'm a bit lost with this one so any help would be much appreciated!

General purpose Python functions in Django

I'm writing a simple Django app and I'm having trouble finding a place for general purpose Python functions (not views). Some of the views in are getting chubby and I want to outsource some calculations to a couple of general purpose functions. Should I create some outside module for that, or it is perfectly normal to put them in What is the general policy about mixing Django-related and generic Python code? I've been thought that generally Django doesn't care, but I can't help cringing when I do that.

In Django CMS how do I access the Page object from the Form of a CMSPlugin?

Posted on April 24, 2014 at 6:56 PM by Stack Overflow RSS

I have a CMS plugin I wrote for Django CMS 2.4 but it is not working now that I've upgraded to version 3.0. This is no-doubt because 3.0 uses front-end editing by default whereas I had only used it from within the admin screens before. The CMSPluginBase I'm using has a custom Form and the options available in a ChoiceField need to be limited by which Site the Page containing the plugin belongs to. I used to be able to pass the request object into the Form and do this to get the Site: current_page is now a None object (wrapped in a SimpleLazyObject) when the plugin loads in the front-end editing popup. I've tried and various other items in Meta and request to no avail.

Django Query Relations Behaviour

Posted on April 24, 2014 at 6:37 PM by Stack Overflow RSS

Okay is there a way to filter the objects so that you only get records with associated records. Is it a right join maybe? Basically, I only want to select records from A that B has a foreign key for whilst using a WHERE clause on B. Am i making it sound more complicated than it is? I don't need the records from B, just the A; maybe a subquery? I'm relatively new to Django's queries and i've only just done some of the simpler stuff.

Django Extend Content perserving old Get Results

I am proficient with python but quite new to django and html. What is the best method to include additional data while keeping data that was previously queried for displayed on the same page?
