Django MongoDB upload file

Django uploads the file and queries the data with Django's own models. Model class, to define a Filefield type of storage file, and add a sentence upload_to, as follows: However, if you use MongoDB, although the document has a Filefield type, but there is no upload_to this parameter, so write a method to store the post file in the local  here's how to store files:

def uploaded_file (f,filename):
    Address = ' c:/users/xxxx/desktop/' +filename
    Destination = open (address, ' wb+ ')
    For chunk in F.chunks ():
        Destination.write (Chunk)
    Destination.close ()

Note: The parameter f is the files file of post, filename is the file name to be stored, the reason is not used a fixed address, because the file type of upload is variable, may also txt, may be jpg, etc.

the upload code in the HTML template:

<form id= "Formid" method= "POST" action= "enctype=" Multipart/form-data ">

<div class= "File-box" >
    <input type= ' text ' name= ' Protextfield ' id= ' protextfield ' class= ' txt '/>
    <input type= ' button ' class= ' btn ' value= ' Browse ... '/>
    <input type= "File" Name= "Proupload" class= "file" id= "Filefield" size= "" onchange= "document.getElementById (' Protextfield '). Value=this.value "/>
    <input type= "Submit" name= "Submit" class= "btn" value= "Upload"/>
</div>

</form>

Template Note: form must be added enctype= "Multipart/form-data", otherwise the file cannot be transferred.  The upload operation that the method performs is called in the view.py

def newproject (Request):
        If request. FILES:
            FileName =request. files[' Proupload '].name
            Uploaded_file (Request. files[' Proupload '],filename)
            post.proadress = filename
    Return Render_to_response (' xxx.html ', locals ())

Description: The filename in the method above is the file name that was uploaded, including the file suffix, such as test.txt. Request. files[' Proupload ') is a file that was obtained with the name Proupload. The result is that the uploaded file is stored in a locally pinned location, and a file name is stored in the database.   Other instructions: currently did not do the download, but the next step is to store all the files in a folder, or by the suffix to separate storage, and then download the time according to the file name in the storage folder traversal, take out the file to be searched for download.
