Minimagick resize image

I'm trying to make a crop with minimagick in Rails and something strange is happening.

The code is as follows:

def resize_crop
    manipulate! do |img|
      img.resize model.width
    end
    # resize_to_fill model.width, 0
  end

The first time I call the function that resizes the image, it returns the following error:

ActiveRecord :: RecordInvalid: Validation failed: Crop Failed to manipulate with MiniMagick, maybe it is not an image? Original Error: identify /tmp/mini_magick20170111-8437-12evsch.jpeg failed with error: identify.im6: Not a JPEG file: starts with 0x23 0

Instead, the next time it runs correctly. I have tried to disable the validation of minimagick, but I see that the problem comes from mogrify.

Any suggestions to solve this behavior?

You did not think about generating a better thumb? if you decide to resize that way I recommend you go to the photouploader app / uploaders / photouploaders driver inside that place there is a commented place: # Create different versions of your uploaded files: here take out # -version: thumb do here take out # -process resize_to_fill: [100, 100] here take out # -end in that way where the parameters are you can decide how soon to leave the resize, then when you do the the image tag <% = image_tag (parametro.img.thumb)% > flames when resize add the .thumb and you will have your image in fixed format
