A (Mostly) Complete Guide to React Rendering Behavior

Bài viết cung cấp chi tiết về cách mà React render hoạt động, và việc sử dụng Context và Redux ảnh hưởng thế nào tới quá trình render của React.

"Render" là gì

Rendering is the process of React asking your components to describe what they want their section of the UI to look like, now, based on the current combination of props and state.

    name = params[:name]

If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

1. Copy content of original credentials rails credentials:show somewhere temporarily.
2. Remove config/master.key and config/credentials.yml.enc
3. Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
4. Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
5. Add and Commit the file config/credentials.yml.enc

Alex Curtis created react-treebeard a data driven tree view for React. I needed to enable users to filter the tree's nodes based on input text. To accomplish this I transform the tree's data using 2 functions when the filter changes and rerender the view:

1. filterTree Given a tree return a new tree keeping only the nodes that meet one of the following conditions:
   1. Has matching text
   2. Has a parent with matching text
   3. Has a child with matching text
2. expandNodesWithMatchingDescendants - Given a tree mark all the nodes with matching descendants as toggled

Here are the aformentioned functions.

# RSpec matcher for validates_with.
# https://gist.github.com/2032846
# Usage:
#
#     describe User do
#       it { should validate_with CustomValidator }
#     end
RSpec::Matchers.define :validate_with do |expected_validator, options|
  match do |subject|
    @validator = subject.class.validators.find do |validator|

How to seed a Rails database with a CSV file

1. Setup

First, Create a folder inside of lib called seeds

Put your CSV file example.csv into the lib/seeds folder. In the example below, the file is called real_estate_transactions.csv

Make sure you've created a resource with the appropriate columns to match your seed data. The names don't have to match up.
