formcreator is a program that creates simple web forms for your programs or python functions, without requiring any webprogramming code.
Just install with
$ python setup.py install
$ pip install formcreator
How it works
An example, if you want to create a simple form for the man program, you can write the code:
from formcreator import * man = Form("man") man += Boolean("Apropos mode?", cmd_opt="-k") man += Text("What manual page?") app = MainApp("Man interface", [man]) app.run()
And run the program above:
$ python app.py
If you go to your browser at http://localhost:5000 you will see the form:
You can use other field types like TextArea, File for file uploads, SelectFile for a widget where you can select a file from a directory, simple numerical types like Integer, Decimal and Float. Is possible to insert any Markdown text between your form fields with the type Doc:
from formcreator import * man = Form("man") man += Boolean("Apropos mode?", cmd_opt="-k") man += Doc(""" Man web interface ================= This is a simple example of a _form_ with two fields. ![Tux image])(http://images.all-free-download.com/images/graphiclarge/linux_tux_1_107532.jpg) """) man += Text("What manual page?") app = MainApp("Man interface", [man]) app.run()
A MainApp can have more than one form inside, just pass the forms like:
app = MainApp("Example", [man, cowsay, convert])
If the first argument to Form is not a string and is a python function, the form data will be used in this function:
from formcreator import * def f(x, d=1): return x**d simple = Form(f) simple += Integer("A number") simple += Integer("Other number", cmd_opt="d") app = MainApp("Function example", [simple]) app.run()
In this case, all fields with cmd_opt arguments will be passed like keywords arguments for the python function. If you want to see contents of one or more directories in the web interface, just pass the dirs argument to Form:
And you will see this on the form page:
This is usefull when the output of your function or program is in a file. In the widget you can download any file created.
You can see a more complex example test_app.py in the repository.
- User access control.
- Save form sessions.
- Display image results.
- Better widgets for file selection.
- Other types of fields (Select, Checkbox, etc).
- Handle cases when program do not terminate.
