Saving external JSON to DB with Rails

前提是你 提交于 2019-11-27 14:05:09
问题 I'm making a GET call to an external source using the gem 'httparty'; here's my Controller.rb: def show response = HTTParty.get('URI') user = JSON.parse(response) user.each {|line| puts line['user']['id']} #the "['user']['id']" is because of the nested JSON object that is returned after the parse. end This returns the correct output in my rails console, but now the question is how do I save the ['id'] to my db?

I want to migrate an existing ASP.NET application to an ASP.NET MVC pattern format. What procedure should I follow? Any step-by-step instructions would be very helpful.

Moving Git repository content to another repository preserving history

喜欢而已 提交于 2019-11-27 02:30:59

I reviewed the other similar post but i only found moving the folder not the contents. I think the commands you are looking for are: cd repo2 git checkout master git remote add r1remote **url-of-repo1** git fetch r1remote git merge r1remote/master --allow-unrelated-histories git remote rm r1remote After that repo2/master will contain everything
