each in each (multiple uses 'each')
Description
obj.each {|a| a.some_method1.each {|b| ... # comes here (enter) } a.some_method2.each {|c| ... # does not enter here } } # tried and that way. also does not go for a in obj for b in a.some_method1 ... # comes here end for c in a.some_method2 ... # does not enter here end end help solve the problem. I’ve been suffering for 2 days.

Can you explain what you are trying to do, and provide a self-contained example? It is not clear from the description or the code what you think the problem is. I can only guess that the object returned by a.some_method2 has an each method that does not yield when called.

In ruby it is in general very rare that deeply nested (and multiple) .each
are necessary.
I recommend to you to use "pp" before you run the loop, such as:
pp obj Perhaps you have an empty Array there - that happens to me sometimes
where I would otherwise get confused why .each is not running.
This is also why I love pp. :)
As Jeremy wrote, it is very likely to assume that something is
not quite right with .each for the object; or it is empty.

selenium
for el in driver.find_elements(xpath: <some_xpath>) for e1 in el.find_elements(xpath: ...) ... end for e2 in el.find_elements(xpath: ...) ... end end I need to do two searches in one pass

You probably want something like:
driver.find_elements(xpath: "...").each do |el| (el.find_elements(xpath: "...").to_a + el.find_elements(xpath: "...").to_a).each do |e1| # ... end end Alternatively, you need an xpath expression that matches both elements you want to select (not sure if that is possible).
As this is not a bug report, I'm going to close this.

this method is not suitable since the 3rd search (find_elements) is also used.
Are you saying this is a bug? you can do issue?
