[Zope] Get file contents.

[Steve Spicklemire]

Hi Jason,

   Here's an external method that I've used to populate a TinyTable
from a comma separated text file. You might at least get some ideas
about how to extract stuff from the file using this....

import string

def ReadFile(self,
             infile,                         # input file.....
             outTableName='defaultTable',    # name of output table
             outTableTitle='',               # title of output table
             outTableColumns='',             # columns for output table
             REQUEST=None,                   # Pass in REQUEST....
             RESPONSE=None):                 # and response...

    if not hasattr(self, outTableName):
        self.manage_addTinyTable(id=outTableName, title=outTableTitle, columns=outTableColumns, REQUEST=REQUEST)

    newTT = getattr(self, outTableName)
    newTT.manage_edit(title = outTableTitle, columns = outTableColumns, REQUEST=REQUEST)
    data = infile.read()
    data = string.replace(data,'\r','\n')
    data = string.replace(data,'\n\n','\n')
    lines = string.split(data,'\n')
    newLines = []
    for i in range(len(lines)):
        line = string.strip(lines[i])
        if line:
            sl = string.split(line,',')
            sl = map(lambda x:'"%s"' % x, sl)
            newLines.append(string.join(sl,','))

    data = string.join(newLines, '\n')
                        
    return newTT.manage_editData( data, REQUEST )


def main():
    class foo:

        def manage_addTinyTable(self, *args, **kwargs):
            pass

        def manage_edit(self, *args, **kwargs):
            pass

        def manage_editData(self, data, REQUEST):
            print "In manage_editDdata"
            print data

    import StringIO

    f = StringIO.StringIO()
    f.write('a,b,c,d\n')
    f.write('d,e,f,g\n')
    f.seek(0)

    print f.read()
    f.seek(0)

    rf = foo()
    rf.defaultTable = foo()

    ReadFile(rf, f)

if __name__=='__main__':

    main()
