mysql - (1406, "Data too long for column ' sr_number' at row 1") 在 Django 中收到帖子并保存到数据库后

Question

任何帮助将不胜感激，我对 Django 和一般的 Web 应用程序开发还很陌生，但到目前为止，我基本上已经能够暴力破解所有内容或自行解决；然而，这让我难住了。

出于某种原因，我的代码似乎试图从我的字段提交整个 html，而不仅仅是它包含的数据，我不确定为什么。

错误消息调试显示:

POST Variable       Value
submitter           u'ccroffor'
csrfmiddlewaretoken u'P8s3aL4bkyzZJWHPitQVEIFS6Lxt3s6e'
sac_id              u'892064'
sr_number           u'3-3016786463'

但是查询显示:

    query   
'INSERT INTO `autoed_submission` (`sr_number`, `sac_id`, `submission_time`, `completed_time`, `submitter`, `submission_helpful`, `submission_link`) VALUES (\'<textarea cols=\\"40\\" id=\\"id_sr_number\\" name=\\"sr_number\\" placeholder=\\"ex... 3-3010581928\\" rows=\\"1\\">\\r\\n3-3016786463</textarea>\', \'<textarea cols=\\"40\\" id=\\"id_sac_id\\" name=\\"sac_id\\" placeholder=\\"ex... 890046, 890052, ...\\" rows=\\"1\\">\\r\\n892064</textarea>\', \'2013-04-20\', NULL, \'<textarea cols=\\"40\\" id=\\"id_submitter\\" name=\\"submitter\\" placeholder=\\"ex... ccroffor\\" rows=\\"1\\">\\r\\nccroffor</textarea>\', \'U\', \'undefined\')'

保存cleaned data , 不是表单域

if form.is_valid():
    data = form.cleaned_data
    newSubmission = Submission(sr_number = data['sr_number'], sac_id = data['sac_id'], submitter = data['submitter'], submission_time = datetime.now(tzz))  #formatting form data to db model
