Allow use of simple formulas in float fields
Formulas in Float Fields
This module allows the use of simple math formulas in integer/float fields (e.g. “=45 + 4/3 - 5 * (2 + 1)”).
Only supports parentheses, decimal points, thousands separators, and the operators “+”, “-”, “*”, and “/”
Will use the decimal point and thousands separator characters associated with your language
If the formula is valid, the result will be computed and displayed, and the formula will be stored for editing
If the formula is not valid, it’s retained in the field as text
Overloads web.form_widgets.FieldFloat (so it works for fields.integer & fields.float)
Uses the eval() JS function to evaluate the formula
Does not do any rounding (this is handled elsewhere)
Avoids code injection by applying strict regex to formula prior to eval() (e.g. “=alert(‘security’)” would not get evaluated)
To install this module, simply follow the standard install process.
No configuration is needed or possible.
Install and enjoy. A short demo video can be found at http://www.youtube.com/watch?v=jQGdD34WYrA.
