solution to struct.error: cannot convert argument to integer

[Maciej Kamiński]

I'm asking about lines in shapefile.py

            name = name.replace(b(' '), b('_'))

            name = name.ljust(11).replace(b(' '), b('\x00'))

            fieldType = b(fieldType)

            size = int(size)

            fld = pack('<11sc4xBB14x', name, fieldType, size, decimal)

            f.write(fld)

in code i have

    shp_writer_lines.field('name','N','5','3')

but it throws error

    shp_writer_lines.save('edges')

  File "/usr/lib/python2.7/site-packages/shapefile.py", line 1033, in save

    self.saveDbf(target)

  File "/usr/lib/python2.7/site-packages/shapefile.py", line 1004, in saveDbf

    self.__dbfHeader()

  File "/usr/lib/python2.7/site-packages/shapefile.py", line 748, in __dbfHeader

    fld = pack('<11sc4xBB14x', name, fieldType, size, decimal)

struct.error: cannot convert argument to integer

because 'decimal' is not converted to integer

My question: is it desired to have in my code:

    shp_writer_lines.field('name','N','5',3)

('5' is str 3 is number witch is not obvious from documentation)

or You want something like:

            name = name.replace(b(' '), b('_'))

            name = name.ljust(11).replace(b(' '), b('\x00'))

            fieldType = b(fieldType)

            size = int(size)

            decimal=int(decimal)

            fld = pack('<11sc4xBB14x', name, fieldType, size, decimal)

            f.write(fld)

i'm glad to see the solution.

Your name variable is a string, you have to pass an int instead!
