It could be combined as follows:

A simple way is to use pandas. Here is how you do it:

I think that the issue here has to do with a misunderstanding. When we talk about daemonizing a process we are essentially saying "This process will now run itself in the background independent of any other process." This can be accomplished, for example, by forking a process to create a new process.

It sounds like that's what you're intending to do here: start your Ruby app which starts a new Rack app that forks into a separate process, then return control to your Ruby app so that you now have your Rack app and your Ruby app running simultaneously so you can use Selenium to browse your Rack app.

That doesn't happen automatically. The daemonize options in Thin can be accessed if you're starting your app using the command line. (because you're starting a new process) But there is no automatic process forking, likely because that would lead to a host of confusing problems. (i.e., if you run your app once and fork a new Thin server on port 3000, and then your Ruby app terminates and you try to run it again, you will already have a forked Thin server running on port 3000 and attempting to start a new one will cause an error because port 3000 is in use)

Essentially, if you want to run a daemonized Thin server then launch it using the thin CLI. If you want to run an ad-hoc Thin server within another app then launch it the way you have above.

And that seems to lead to the real answer: your explanation and code sample indicate that you don't actually want a daemonized Thin server running in the background. You want a Thin server that runs in a separate thread and returns control to the main thread so you can use Selenium, and when your app terminates the Thin server terminates as well.

If I'm wrong about that, and if you actually want a daemonized Thin server, then you're going about it the wrong way. You should tread the Thin server as one app and the Selenium app as another app. (launch and manage them separately, not as a single Ruby app)

But if I'm right about that, then it should be as simple as:

If I understand your question correctly you want to be able sort the data based on betting type but the value of betting types are not sortable if used as a String variable. The solution would be to converting them into enum types with raw values and then sorting the array based on those raw values. Here is an example:

You can set RETRY_TIMES directly in your spider code (docs)

You can do this by simply changing the RETRY_TIMES setting to a higher number.

You can read about your retry-related options in the RetryMiddleware docs: https://docs.scrapy.org/en/latest/topics/downloader-middleware.html#std:setting-RETRY_TIMES

I inspected the website from where you are trying to implement pagination. There is an attribute of [start] in the URL. If you inspect multiple requests, you will notice that it gets incremented by 10 in every iteration. Here, you can create a loop where 10 is incremented to the existing number and then launch the request. You can use the library of from w3lib.url import add_or_replace_parameters and change the parameter by incrementing it by 10 in each iteration. You can change the existing response.url and create a Request through it using from scrapy.spiders import Request.

The question that remains is where should the loop end? I didn't tackle this question and left it for you. Best of Luck! Check this image to understand the parameter that changes

Replace next_page_number = str(next_page_number) with this:

next_page_number = next_page_number[0]

This works because next_page_number is a list and next_page_number[0] will select the first item of the list which is the string '10'. When you did str(next_page_number), you simply make a string representation of the list which will include the brackets.

If you look in your network panel when you load that page you can see the XHR and the headers it sends

So it looks like he just copied those.

In general you can skip everything except User-Agent and you want to avoid setting Host, Connection and Accept headers unless you know what you're doing.
