Question

from django.db import models
from django.core.urlresolvers import reverse


class Gallery(models.Model):
    Title = models.CharField(max_length=250)
    Category = models.CharField(max_length=250)
    Gallery_logo = models.CharField(max_length=1000)

    def get_absolute_url(self):
        return reverse('photos:detail', kwargs={'pk', self.pk})

    def __str__(self):
        return self.Title + '_' + self.Gallery_logo


class Picture (models.Model):
    Gallery = models.ForeignKey(Gallery, on_delete=models.CASCADE)
    Title = models.CharField(max_length=250)
    Artist = models.CharField(max_length=250)
    Price = models.CharField(max_length=20)
    interested = models.BooleanField(default=False)

    def __str__(self):
        return self.Title

我收到此错误

您将import React, { Component } from 'react'; import { ... Dimensions, ... WebView, } from 'react-native'; let ScreenHeight = Dimensions.get("window").height; let ScreenWidth = Dimensions.get("window").width; class App extends Component { render() { return ( <View style={styles.container}> ... <WebView source={{uri: 'http://foo.com'}} style={{height: ScreenHeight, width: ScreenWidth}} /> ... </View> ); } } ... const styles = StyleSheet.create({ container: { backgroundColor: '#bbb', flex: 1, }, ... }); AppRegistry.registerComponent('myApp', () => App);作为集传递给kwargs，而它应该是字典：

reverse

反向重定向不起作用，但将数据插入db
