Coming from the world of PHP and WordPress, I am trying to implement a form where, I upload a bunch of images attached to a post. However, I want to insert images within the body of the post.
The flow should be:
- Fill out the form fields
- Upload images.
- The image field should have the option of been inserted into the post body.
- On hitting submit, the controller should save the form with the images embedded in the post body.
Any thoughts/suggestions?
Your workflow would be simple to implement, I would tackle resource uploads inside a separate controller since you may want to extend it later and you don’t want the upload logic cluttering up your Posts controller. You can use some of the great gems Ruby has for images uploads like:
Once you have image uploads working you can move on to integrating it with your Posts. Set up a relationship between your Uploads controller and the Posts controller. I would use a has_and_belongs_to_many relationship which would enable you to record what images are used in what posts.
Then the only thing that’s left is to create a form on your Posts create page for uploading images. There are many ways to do this but I would start out with a simple static form as a proof of concept in the beginning and then move into using AJAX (text version) and some JavaScript to make the upload form more user friendly.
Once you have that working there are other modifications you can make including adding support for a layout engine like Markdown or Textile which would make adding style to Posts easier and potentially have better support for adding images into a post body.
Anyway, these are just high level concepts and I hope that they are enough to point you in the right direction. If you need help with the basics feel free to search StackOverflow and you can find similar questions or if you need additional clarification you may comment on this post.
