heroku

问题 I am a Rails beginner and i see some issue while deploying to Heroku. Earlier i used SQLite3, later when i understood that i needed postgresql i installed the same and work on local machine. One deployment went fine after migrating from sqlite to postgresql. Now i see some issue. Heroku logs, Gem file and Database.yml details are as below. Can some one help me in this please. Advance Thanks...!!! Part of Gem file: group :development, :test do gem 'pg', '~> 1.0.0' gem 'rails_12factor' #gem

问题 I have my app working just fine on my local environment at localhost:3000. It is pulling data from my local postgres db, however I don't appear to be updating the production environment. My welcome page is viewable on my https://gcl.herokuapp.com page, but when I click the nav link to view another page I get an error, I'm assuming because that page calls on data from the db, which it cannot find. I'm doing $ rails db:migrate RAILS_ENV=production I get the following output in Terminal: (0.2ms)

Everything works locally (e.g. rake assets:precompile ), but on Heroku my push fails with the following: Running: rake assets:precompile adding placeholder rake aborted!

问题 I'm trying to deploy a Flask application to heroku and I'm suspicious that perhaps the Procfile is to blame. I'm not sure if I wrote it correctly, and liike many other stackoverflow users I had a hard time finding documentation to clarify what the syntax of the Procfile is supposed to be. I'm using gunicorn just cuz tutorials seemed to recommend it. First off, a screen cap of my file tree for this Flask app... Correct me if I'm wrong, but I believe that my flask app module should be named

问题 I have been trying to build a Rails API with an integrated React front end and deploy it to Heroku. I am using create-react-app to build the React app in a directory called "client" within the Rails project folder. I run the Rails api on localhost:3001 and the React app on localhost:3000. And it works when I deploy it to Heroku except when I am using a React Router url and try to refresh the page, or if I try to copy and paste the URL in the browser. It's the same result on multiple browsers.

问题 I created an React app (using CRA) with Nodejs backend. Now I tried hosting it. (I've hosted few apps with same stack but didn't faced any issues).
