Notes on problems and solutions when using the fleximage plug-in ror

1. uninitialized constant filecolumn: magick: image:

Cause: rails_file_column and fleximage both exist

Solution: Delete the rails_file_column plug-in. With fleximage, rails_file_column is no longer needed.

 

2. Add Chinese watermarks to display garbled characters

Reason: rmagick lacks Chinese Fonts

Solution: add the font parameter to the operate function, as shown below:
: Font = 'public/images/simsun. TTC'

Note: copy the C:/Windows/fonts/simsun. TTC file to the public/images directory of the project. I used the UTF-8 character set and did not try the gb2312 character set.
