Heroku Postgres Database Backup

By -
Hi I have Heroku ,And I face lot of problems in upgrading the models based on the changes .

http://www.panhidhalyrics.com/

Based on lot of discussions  the migrations of Heroku ,  doing in local and apply them in the remote after pushing not gives me the expected outcome. Rather application ends up in  errors.

 1. $ heroku run python manage.py makemigrations panhidhaapp

 2. Push the changes to git  

 3. $ heroku run python manage.py migrate

The other thing we can do it  we change the Model and apply the change in the DB manually trough PgAdmin

Frist you need to login and get the db Cardinals
https://id.heroku.com/login

Navigate to the following location
Application >> Addons >> Heroku Postgres :: -- >> Overview Section



Open PgAdmin and  give the detail as it is .The value in the database will be given to the maintenance db in pgAdmin.

 

After login you have to navigate to your own database which does not indicated the access restriction by cross mark.



Do the model changes in the model.py file and do the same changes in the mapping db table.

React-qill  is a great free package which can be used for design editors. However, if you are using the image upload feature, there is a problem of integrating resize package. This was discussed in may treads and I was able to find the best approach integrate it with react-starter-app. https://www.npmjs.com/package/quill-image-resize-module If you use the following code, import Quill from ' quill ' ; import { ImageResize } from ' quill-image-resize-module ' ; Quill . register ( ' modules/imageResize ' , ImageResize); const quill = new Quill (editor, { // ... modules : { // ... imageResize : { // See optional "config" below } } }); The following error is common. TypeError: Cannot read property 'imports' of undefined var d = window.Quill.imports.parchment In order to overcome the issue , you have to update the node_modules/react-scripts/config/webpack.config.
