问题 I have a rails project which uses twitter bootstrap and sass. The scss files are structured into folders so I have a better overview. Now I want to define a file for global variables which contains my colors etc. and pass those values down to other files so I have less redundant code. While all code is properly imported and applied, variables don't work. Here is the current setup: stylesheets/application.css.scss /* *= require_self *= require_tree */ /* stylesheets/ | |– base/ | |– _reset

问题 Im using sqlite db in a sample rails application. From my users table, i have cleared all records using User.delete_all . But now whenever i insert a new record in the table using User.create , the id is starting at a value which is one more than the id of the last record which was there in the table. For example, if my table had 5 records and i cleared all, then when i do User.create, its starting at id 6. Is there any way i can make the id start from 1 again ? Thank You 回答1: Similar

问题 I tried using a web app that would access h20 flow using REST API routes and when I tried to delete a frame (it would delete the frame after predicting), this happens: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://139.59.249.87:54321/3/Frames/1i3uso. (Reason: CORS header 'Access-Control-Allow-Origin' missing). I'm using ruby rails in order to build the web app. Any advice? I used this route: DELETE /3/Frames/{frame_id} and this coffee

问题 I am trying to write an integration test in which I must check the visibility of an element on button click. The code works perfectly in one machine and failing in the other. The element is displayed until the data comes from the backend. So its visibility depends on the speed of the machine also. Is that the problem? This is the code: assert page.has_css?('#my_element_id') assert find('#my_element_id', visible: true) But I am getting an error: expected false to be truthy . Is there any other
