Question

我有一个模型，并添加了一个Form FileField来获取文件并保存特定对象的所有内容。应该读取，解析文件中的内容并将其存储到模型的synonym_name。

model.py

molecule = models.ForeignKey('MoleculeDictionary', blank=False, null=False)
synonym_type = models.ForeignKey('SynonymType')

synonym_name = models.CharField(max_length=50, blank=True)
def __unicode__(self):
        return u'%s' % (self.synonym_name)

这就是我将Form字段添加到模型（admin）页面的方法。

form.py

    from django.forms import ModelForm
    from django.forms import *
    import pdb
    import os
    from django.core.files.uploadedfile import SimpleUploadedFile
    from django.core.files import File
    from idg.models.molecule_synonym import MoleculeSynonym


    class MoleculeSynonymForm(ModelForm):
        file_upload = FileField(required=False)
        print "YES" 
        def save(self, commit=True):
            print 'saving...'
            file_upload = self.cleaned_data.get('file_upload', None)
            file_upload.seek(0)
            with open("../../Downloads/model_file_upload.txt", 'r') as f:
                model_file = File(f)
                names = model_file.read()
                print(names)

                form = MoleculeSynonymForm(names)

                return super(MoleculeSynonymForm, self).save(commit=commit)
            #

        class Meta:
            model = MoleculeSynonym

我有两个问题：

如何为选定的同义词类型和分子将名称保存到Synonym_name。我用sqlite。我当前的代码不会抛出任何错误：

分子同义词＆＃34;＆＃34;成功添加。

如何获取文件的＃34;完整路径＆＃34;没有在公开声明中对它们进行硬编码。

更新：试过这个： 我知道这可能是彻头彻尾的愚蠢：

 try:
    synonym_name = MoleculeSynonym.objects.create(synonym_name=names)
 except:
    synonym_name = None

    print synonym_name

    synform = MoleculeSynonymForm(instance=synonym_name)

print语句打印无。

我没有得到你想要的东西，但如果这有助于看看：

class MoleculeSynonymForm(ModelForm):
    file_upload = FileField(required=False)

    class Meta:
        model = MoleculeSynonym

    def clean_file_upload(self):
        file_upload = self.cleanded_data['file_upload']
        if file_upload:
            model = YourModel()
            model.file = file_upload
            model.save()
        else:
            raise errors

将YourModel替换为您的模型和文件以及模型文件字段。
