Additions and deletions of django-mysql table

1. Add Data

call this route to perform a Modelscaozuo processing method

The first instantiation of a class

classModelscaozuo (View):" "database additions and deletions change" "    defget (self, request): article=article () Article.title="How to add a table of data that has multiple fields"article.content="instantiate model, assigning by. attr"Article.message="persist data using Django's Save"Article.save ()returnHttpResponse ("%s<br>%s<br>%s"% (Article.title, article.content, Article.message))

The second type does not instantiate

classModelsCaozuo1 (View):" "database additions and deletions change" "    defget (self, request): article (title="add data is not instantiated, use the class directly", Content="66666666666", Message="also persist data through Django's Save"). Save ()returnHttpResponse ("%s<br>%s<br>%s"% (Article.title, article.content, Article.message)) # no data?

2. Querying data

Querying all data in the article Table Article.object.all ()

PS: Returns multiple data (list collection of article instances, for in)

class ModelsCaozuo2 (View):     " " querying all data for a article table ""    def get (self, request):         = Article.objects.all ()        print#  queryset instance  list can  
<article:article Object>]        return'mysql_select.html' , locals ())

mysql_select.html  page Get Properties

< Body > {% for con in content_all%} The data in each table corresponds to an instance of the article Class con    {{Con.title}} < BR >     {{con.content}}<br>    {con.message}}  <br>{% endfor%}</body>

Querying the article table for single Data Article.object.get ()

PS returns only one piece of data (so it only returns a single article instance), if the data has multiple or no error

class ModelsCaozuo3 (View):     " "  "    def  get (self, request)        :#  PK Query        by primary key # ID query   General ID field by ID set as primary key        return ' mysql_select1.html ', locals ())
