ruby on rails - How to dump the database to yaml file with content '<% abc do %>ddd<% end %>'? -

In my database, there is some text content, one of them is:

  & Lt;% ABC%> Ddd & lt;% end% & gt;  

When I put it in yaml with to_yaml () , then it is:

  Content: | - & lt;% make ABC%> Ddd & lt;% end% & gt;  

And then, when I use rake db: fixtures: load , then such error occurs:

  The exact error was: NoMethodError: Undefined method for main 'ABC': object  

I have checked the source of the db: fixtures: load , and found That text will not be considered plain material, but the erb template, so it will try to find and execute the 'abc' method.

How can I fix this? I think the default 'to_yaml' should not be used.

We '& lt;%' such as:

I am doing now Before I wrote the file, I did not call '<'% all '& lt; %% 'but it does not always work correctly. If there are some non-English pigments in the material, the content will be dumped as 'binary', not the text. Then when read back, '& lt; %% 'will not be converted to' & lt;% '
