ruby-on-rails-6

问题 Trying to build a new rails 6 application from scratch to replace a rails 5.2 application. Trying to use webpacker with foundation-site jquery and coffeescript After a bunch of searching I've got everything loaded with webpacker. It appears to be very (maybe too) flexible in that examples use different approaches. Everything works (foundation does x-grid, callouts etc, jquery loads and I can log jquery objects, coffeescript compiles) except jquery events don't seem to fire or build a listener

问题 Just created a new Rails 6 app, and I am trying to allow adding images to an active_storage blob instead of replacing them, through a form generated with rails scaffold. Followed the documentation (https://guides.rubyonrails.org/active_storage_overview.html#has-many-attached), using #attach into my controller, but it leads to an error page and keep the "default" behavior of replacing all the images instead of adding new images. Using Rails 6.0.0 with active_storage 6.0.0 I first made a Page

问题 I'm rendering a form that utilizes the ActionText input rich_text_area, which is the Rails implementation of the Trix WYSIWYG rich text editor. It's been working fine until I started refactoring my views to use a layout, where the form content can yield different forms. The form renders fine except for the rich_text_areas, which both disappear. Removing the code required to make this a layout returns it back to normal. My code is below. I'm rendering a form as a partial with the following

问题 This looks just like the question @rossta answered for Gmaps, but I don't understand the problem and answer well enough to make his suggestion work. The error is: Uncaught TypeError: L.timeline is not a function at Object.success (mapTwo.js:14) Line 14 is var timelineData = L.timeline(data_data, { . Complete code below. I removed the leaflet gems that work in Rails 5.2 and in console yarn add leaflet yarn add leaflet.timeline and code: // app/javascript/packs/application.js import "core-js

问题 I'm currently trying to implement a datepicker into my application, the problem is that there is no documentation on how to add the jquery-ui-rails gem through webpacker. Probably there is another way to add gems or another gem that would fit my needs? 回答1: You no longer need to add javascript libraries as gems (which are managed by the bundler). Instead, you add them with yarn and they are managed by webpack (which is enabled by adding the webpacker gem to the Gemfile). The following steps

问题 I'm trying to install jQuery in Rails 6.0.0.rc1 via Webpack and I'm not sure what I'm missing but I'm getting the error $ is not defined in the browser console despite being able to compile jQuery. I've added jQuery with yarn add jquery , so my package.json looks like this { "name": "muladeseis_app", "private": true, "dependencies": { "@babel/preset-react": "^7.0.0", "@rails/actioncable": "^6.0.0-alpha", "@rails/activestorage": "^6.0.0-alpha", "@rails/ujs": "^6.0.0-alpha", "@rails/webpacker":

问题 Climbing the learning curve with Webpacker and Rails 6. I've installed Boostrap 4 using Yarn and Webpacker. When I try play with Bootstrap components in a browser's JS console then I get: TypeError: $.fn.button is undefined . If I remove the Yarn installation add a Bootstrap CDN link in the head of the HTML (the old way) everything works fine. When I remove the CDN links and revert to using Webpacker I get back to the error above. Here is my Webpacker setup: // package.json { "name": "depot",
