问题 I am working on a donation form for a charity and they have requested a monthly donation plan where the user can choose whatever amount they would like to give. I know I can make individual plans (i.e. if they said monthly donations of $5, $10, or $20 dollars) I could make three different plans and subscribe users to them. Is there a way to avoid making new plans for every varying subscription amount? 回答1: The Stripe documentation recommends using the quantity parameter on the subscription.

问题 I am quite new to the Ruby, and I ran into problem with defining an object of a class. If I understand correctly, def initialize should ask for three calues, but the code compiles with an error that three is given, but it expected zero values. I thought the mistake there would be in attr_accessor, but a quick test showed that this is not a case. The ruby version is 2.6.4 test.rb:16:in `new': wrong number of arguments (given 3, expected 0) (ArgumentError) class Battler attr_accessor :health,

问题 I'm trying to enforce a company policy, taking these assumptions: There are only 3 available upstream branches: master, version/* and hotfix/*. Master branch accepts only non-forwarded merge commits. Version and Hotfix branches accept only fast-forward/rebased commits. Master branch must only be merged into from Version or Hotfix branches. Version and Hotfix branches must diverge from Master branch directly. So far this is what I come up with: #!/usr/bin/env ruby # Encoding: utf-8 $oldrev,

问题 the development.log in my application has never worked since the beginning of creating the application. I pull other projects from github, run them and the logs work perfectly fine. the SQL queries don't get logged to the server console either.

问题 I have a problem where I believe my sqlite3 database is too big. I imported around 100,000 records into a database and I was able to "git push" and "git push heroku." Now I probably made a mistake and imported too many records...500,000. I was able to push to git(and now it states around 336MB in bitbucket) and that seems to work but when i push to heroku this is what i get: /workspace/new_foodback$ git push heroku Counting objects: 26, done. Delta compression using up to 8 threads.
