fix execution of execute and load_next_page method #587

Open deepprajapati18 opened 3 years ago

deepprajapati18 commented 3 years ago

There is a bug while working with Facebook request API, that is not giving all the elements as it is returning 25 elements. So by checking the execute method of the FacebookRequest, I notice one thing that, it is calling only for the first paginated elements and the default returning limit is 25 so It is returning only first page data, and will not check for the next page.

So in the execute method of FacebookRequest, there is a method called load_next_page which is the method of the Cursor, which is calling the graph API but it will run only for the first time and it will not check the next page of data. So I updated it like: add a while loop and check the status of the load_next_page and store the result in the status. So if the status will True then It will check the re-execute the load_next_page, which will call the next page graph API as on every execution of load_next_page, URL-PATH which is self._path, will update to next page URL.

And this process will continue until there is no next Page URL. If there is not Next Page URL then self._finished_iteration from Cursor will set to True and when the load_next_page will run again then it first check if self._finished_iteration then return False.

And we will store this value in the status which is in the loop of the execute method of FacebookRequest. So when the status will False break the loop and continue the process as it is already there.

was this ever fixed?

GoooGu commented 10 months ago

This actually isn't an issue as long as you iterate the returned cursor from execute(). The Cursor object will load_next_page() for you if the queue is empty.

GoooGu commented 10 months ago

Now the real problem is how to make this load_next_page() faster. If I have 10k ad creatives, how do I fetch all the rows quickly without taking over 80 seconds.
