Pass Image Read From OpenCV From Django To Reactjs and Show it on Website in Real Time
I have python snippet which gets live feed camera video from IP camera: Load each frame using opencv's read function and pass the loaded frame to face detector. Processed frame with bounding boxes received from a function(in a variable). It show the resultant frame using cv2.imshow function. Now my goal is, instead of using opencv's imshow function I want to show it on website in real time as it's working cv2. So now i am using django-react simple application to show it on website. BUT my question is that how we can show the processed image( in variable array) and pass it from django views.py to react and show it on website page. I have googled so many times but couldn't find anything related to this. Thank You. -
How to create an attribute of model which is consists parts of other attributes
Let's I have a model. class Trips(models.Model): from_point = models.CharField(max_length=50) to_point = models.CharField(max_length=50) trip_desc = models.TextField(max_length=250) seats = models.CharField(max_length=20, blank=True, null=True) price = models.PositiveIntegerField() created_time = models.DateTimeField(auto_now_add=True) new_attribure= ? How to create an attribute so when we're creating an instance of Trips it will take part of attributes from_point, to_point + some unique string? For example: obj1 = Trips('Moscow', 'Dushanbe', 'Some_description', '4', '100', 'date_time', 'MosDushUniquestring') In this case it's taking three first characters of from_point, to_point attributes + some unique string. The idea is to have a unique attribute which has some meaning. -

Django HTMLCalendar Previous and Next Month won't show

Loading Data from an external API into Django models advice
This is more of a design than technical question. What i am doing is trying to present external API data to a user in the form of a table. The data is a list of products (description, price, etc). The user can select the products that they would like to buy from the table (i.e: select the rows in the table) and then proceed to the next page where a table of only the products they have selected is show. (its almost like an ecommerce cart but instead of adding items one-by-one, multiple items can be added at once. ) The API of available products is always changing and growing as new products are added, also the products are one-offs, as in there is only 1 of them and a second user can not select a product once somebody else has chosen it. At the moment i can do this, however it is all on the client side because i am using Ajax to pass the JSON object straight into the html table. From there I use Jquery and javascript to select the table rows by class toggling and complete the process. (It is very 'hacky'). However, doing it this … -

Elastic Beanstalk doesn't deliver all environment variables to application
I'm running a Django app on Elastic Beanstalk. Previous version of my app had 11 environment variables in Elastic Beanstalk and worked fine. Latest version requires two more. I have spent several hours wondering why the app doesn't work anymore, before noticing that two environment variables do not exist in os.environ! One of the missing variables is a new variable added today, and the other one worked earlier. Second new variable can be found in os.environ. Length of the variables don't come close to the maximum of 4 KB. How is this possible? -

Showing model entries as a form in a table
I have a model which has data that i need to show to a user in the form of a table. The user can select rows in the table and then proceed to the next page with only those items. I think the way to do this with django is to crate a table where every row is a form, when a user clicks on a row it updates the status of that entry in the table to be "Selected" and when the user proceeds to next page, a new queryset with only entries with a status of "Selected" are shown. Does this make sense? Or is there a better way to achieve this? -
