Design

Title for application Header for homepage Homepage lists all recipes as index - links to each recipe with delete and edit option

Recipe page: image at top of page Table: Ingredients on left, Directions on right Notes below

Implementation

Will need erubis for erb files Will use bcrypt for hashing passwords Start with using an external location for images

Delete recipes

Create delete route
Create delete method - access id from session hash & delete corresponding key-value
Set session message: "'recipe name' deleted."
Add delete button to view_recipe.erb

Add flash message div to layout.erb Style flash messages

Check for pre-existing recipe with identical name. Preserve entered data when notifying.

When saving ingredients and directions to session from form, break them into separate elements in an array for each line break. Then render them back to user as separate lines.

Create edit functionality

make edit routes
view existing content
save to session

Option to add or change photo

if no photo present, display 'add photo' button
if photo exists, display 'replace' button
Add 'delete' image option
Resize image on display

Fix grid styling of recipe page

Add Bcrypt gem
Create credentials document
Access credentials to compare username and password or write new info to it
verify username for registration doesn't already exist
create compare credentials method
create write new credentials method

Write a method to display a flash message if trying to access a path that doesn't exist. Write a method to prevent accessing /recipe path unless the user is signed in. Display a message 'You must be signed in to do that.'

Store recipes as individual entries in recipe document within file structure recipe document should be labeled for the user (new document for each user)

check if file exists: create or access it
- name for user
store info within a YAML hash
- Each recipe should get its own entry in the hash. Key is the Id. (as an integer not symbol)
- title
- ingredients
- instructions
- image - either link as string or filename to create path to image in directory
- notes - empty string if blank Store images as separate files within file structure if uploading an image - images should be in folder labeled for user Files and images should have paired name/id so can be accessed simultaneously to display to user and deleted at the same time

Create new user - store username and hashed password in users.yml file. there is no file for recipes yet. create recipe file once first recipe is added. in add route, check if the file already exists. if no, create if yes, write to existing

Display welcome screen sign in or register if signed in add a recipe or recipes add recipe checks either loads or creates recipes document named for user

Need edit button for uploaded images
adjust edit route for content
simplify edit route
change edit route to not require capitalization

Working with deleting files

FileUtils.rm_rf - removes entire directory even if it's not empty
FileUtils.rm_r - removes entire directory even if it's not empty
FileUtils.rm_f - force remove; doesn't do anything Errno::EPERM at /delete/1 Operation not permitted @ apply2files - public/images/newuser5/
File.unlink
FileUtils.remove_file
File.delete

these errors were because I was not accessing the contents of the hash correctly (omitting the key prevented me from accessing the file name). After correcting that, File.delete worked perfectly!

verify uploading file if 'upload' / link if 'link'
show edit link for view_recipe page with uploaded images

Finalize image edit page
