# lua-resty-mvc

**You don't need that complicated MVC framework!**

With just a plain folder with several simple files, you can enjoy basic but most frequently used MVC features.

# Dependencies

[lua-resty-mysql](https://github.com/openresty/lua-resty-mysql)

[lua-resty-reqargs](https://github.com/bungle/lua-resty-reqargs)

# Quick start

Config your database in `lib/resty/mvc/query.lua` and try to start from `nginx -p . -c nginx.conf`, and visit [http://localhost:8080/init](http://localhost:8080/init)

# Api taste

Below is five models representing five database tables. Why so many tables?  Because I want to show you how powerful

the MVC is.

## Model relations 

|Model_name|col_1|col_2|col_3|col_4|col_5|

|---|---|---|---|---|---|

|Moreinfo|weight|height||||

|Detail|sex|age|info::Moreinfo|||

|User|name|money|detail::Detail|||

|Product|name|price||||

|Record|buyer::User|seller::User|product::Product|count|time|

symbol `::` means a foreign key relation

##Api example

if you're curious, please run this project and visit [http://localhost:8080/test](http://localhost:8080/test) to see

what are the final SQL statement.

```

User:where()

User:where{}

# Synopsis

Code below shows how easy it is to write a user register logic code.

```

location = /register {

    content_by_lua_block{

        local UserForm = require"forms".UserForm

        local User = require"models".User

        local req = ngx.req

        local form;

        if req.get_method()=='POST' then

            req.read_body()

            form = UserForm:instance{data=req.get_post_args()}

            if form:is_valid() then

                local cd=form.cleaned_data

                local user = User:instance(cd) 

                user.age = 22 -- set some value before saving to database

                user.score = 150

                local res, errors = user:save(true) -- `true` means insert a row to database, 

                if not res then

                    return ngx.print('Fail to create user, '..table.concat(errors, '
'))

                else

                    return ngx.print(string.format(

                        'Congratulations! You have created a user successfully! 
'

                        ..'id:%s, Name:%s, Password:%s, Age:%s, Score:%s, Create time:%s.'

                        ..'
now please try login
', 

                        user.id, user.username, user.password, user.age, user.score, user.create_time))

                end

            end

        else

            form = UserForm:instance{}

        end
