ruby on rails - Assigning an exception to a variable in pry -

-

So I'm trying to use pry to debug a method_missing in my Rail app : [5] pry (# & lt; Travel Agreement & gt;) & gt; E-name: Undefined local variables or # & lt; Method 'E' for Travel: Travel: 0x007fa3f30d13c8 & gt;

This is my code 

  21: define_method (save_method) Do 22: If "@ # {method_name}" exists? 23: Start 24: self.send ("# {attribute} =", time .pars (instance_variable_get ("@ # {method_name}"))) 25: rescue = & gt; E = & gt; 26: binding.pry    
 
 
 You always use the last exception through the global variable Can  $! . See if your breakpoint works. It's possible that you have a breakpoint set elsewhere, and are actually debugging the wrong line.

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
