Issue
I am trying to combine the item with item field similarIdeas which is a list right now I am using requests to get the data but I need to yield those requests by chaining them and yield one single item not sure how to do it correctly. Here is my code using requests module:

I tried to join the requests by adding item to meta in the requests but it didn't worked as expected it is only collecting only one similarIdeas and it should be at least 25 or 24 and giving a lot of duplicates despite the fact I haven't place dont_filter=True. Here is my code trying chaining requests:

Solution
Your second example is really close. THere are just a couple of things I would recommend and one thing that is missing:
You should use
cb_kwargsto pass data between callback methods, instead of using themetadict. Both will work but using the cb_kwargs is what scrapy recommends in this situation and I believe it makes it more readable and requires fewer lines of code.When running your second example I ran into quite a few situations where the dupelicates filter was triggered. When chaining requests like this having single request filtered will likely mean that item will never be yielded. In order to avoid this you should make your
space_urlsvariable a set instead of a list so you know each url is unique, and you should also add thedont_filterargument to the requests in yourparse_similar_ideasmethod.THe last and most important point is that you are yielding an item at the end of every call to
parse_similar_ideas, which means you are yielding the same item once for every single url in thespace_urlslist, and the only thing that is changing is the number of items in thesimilarIdeasfield in your item. What you actually want to do is only yield the item once there are no more urls left inspace_urls, then you are only yielding the item once at the very end of the chain.
The example below implements the above points and creates the output you are expecting. You will want to add your custom_settings back to the example though.
