Web2py Plugin for easy conversion of slow virtual columns for agile columns case

This plugin uses the standard module dis, allowing disassembly of python code and building columns in sql case

[pt-Br] Web2Py Plugin para fácil conversão de colunas virtuais lentas para colunas sql case ágeis

Este plugin usa o módulo padrão dis, que permite a desmontagem (disassembly) do código python e a construção de colunas case em sql

Eg. (Ex):

```python

def main():

  from case import Case

  def myfunc():

    if db.mytable.myfield == 0:

      return 'A'

    elif db.mytable.myfield == 1:

      return 'B'

    else:

      return 'C'

print(db()._select(db.mytable.ALL, Case(myfunc))

```

```sql

SELECT CASE WHEN (mytable.myfield = 0) THEN 'A' ELSE CASE WHEN (mytable.myfield == 1) THEN 'B' ELSE 'C' END END AS myfunc FROM mytable

````

```python

  def myfunc1():

    if db.mytable.myfield == 0:

      if db.mytable.myfield1 == 'a':

        return 1

      return 0

    return False

  myCol = Case(myfunc1)

  myCol << "other_name"

  print db()._select(db.mytable.ALL, myCol)

```

```sql

SELECT CASE WHEN (mytable.myfield = 0) THEN CASE WHEN (mytable.myfield1 == 1) THEN 1 ELSE 0 END ELSE 'F' END AS other_name FROM mytable

```

```python

def myfunc3():

  if db.mytable.myfield >= 5 or db.mytable.field < 2 :

    if db.mytable.myfiedl1 == 0 and db.mytable.myfield2 == 1:

      return 2

    return 3

  return 1

```

```sql

SELECT CASE WHEN ((mytable.myfield >= 5) OR (mytable.myfield < 2)) THEN CASE WHEN ((mytable.myfield1 == 0) AND (mytable.myfield2 == 1) THEN 2 ELSE 3 END ELSE 1 END AS myfunc3 FROM mytable
