添加用户编辑区
1.修改Admin.index()
public static void index() {
List<Post> posts = Post.find("author.email", Security.connected()).fetch();
render(posts);
}
2.修改页面 app/views/Admin/index.html
#{extends ‘admin.html‘ /}
<h3>Welcome ${user}, <span>you have written ${posts.size() ?: ‘no‘} ${posts.pluralize(‘post‘, ‘posts‘)} so far</span></h3>
#{list items:posts, as:‘post‘}
<p class="post ${post_parity}">
<a href="#">${post.title}</a>
</p>
#{/list}
<p id="newPost" >
<a href="#"><span>+</span> write a new post</a>
</p>
个人展示页完成
3.添加新增Post页面
Admin新增Action
public static void form() { render(); } public static void save() { // Not implemented yet }
添加路由
GET /admin/new Admin.form POST /admin/new Admin.save
创建页面 /app/views/Admin/form.html
#{extends ‘admin.html‘ /}
<h3>Write, <span>a new post</span></h3>
#{form @save()}
#{ifErrors}
<p class="error">
Please correct these errors.
</p>
#{/ifErrors}
<p>
#{field ‘title‘}
<label>Post title:</label>
<input type="text" name="${field.name}"
value="${post?.title}" class="${field.errorClass}" />
#{/field}
</p>
<p>
#{field ‘content‘}
<label>Write here:</label>
<textarea name="${field.name}"
class="${field.errorClass}">${post?.content}</textarea>
#{/field}
</p>
<p>
#{field ‘tags‘}
<label>Enter some tags:</label>
<input type="text" size="50"
name="${field.name}" value="${post?.tags?.join(‘ ‘)}" />
#{/field}
</p>
<p>
<input type="submit" value="Publish this post to the blog" />
</p>
#{/form}
Admin.index.html 添加Post按钮
<p id="newPost" >
<a href="@{form()}"><span>+</span> write a new post</a>
</p>
3.完善Admin.Save方法
public static void save(String title, String content, String tags) { // Create post User author = User.find("byEmail", Security.connected()).first(); Post post = new Post(author, title, content); // Set tags list for(String tag : tags.split("\\s+")) { if(tag.trim().length() > 0) { post.tags.add(Tag.findOrCreateByName(tag)); } } // Validate validation.valid(post); if(validation.hasErrors()) { render("@form", post); } // Save post.save(); index(); }
新建Post可以保存了
4.修改Admin.form
public static void form(Long id) {
if(id != null) {
Post post = Post.findById(id);
render(post);
}
render();
}
修改Admin/index.html
#{list items:posts, as:‘post‘}
<p class="post ${post_parity}">
<a href="@{Admin.form(post.id)}">${post.title}</a>
</p>
#{/list}
添加Route
GET /admin/myPosts/{id} Admin.form
GET /admin/new Admin.form
5.修改 app/views/Admin/form.html
#{extends ‘admin.html‘ /}
#{ifnot post?.id}
<h3>Write, <span>a new post</span></h3>
#{/ifnot}
#{else}
<h3>Edit, <span>this post</span></h3>
#{/else}
#{form @save(post?.id)}
#{ifErrors}
<p class="error">
Please correct these errors.
</p>
#{/ifErrors}
<p>
#{field ‘title‘}
<label>Post title:</label>
<input type="text" name="${field.name}"
value="${post?.title}" class="${field.errorClass}" />
#{/field}
</p>
<p>
#{field ‘content‘}
<label>Write here:</label>
<textarea name="${field.name}"
class="${field.errorClass}">${post?.content}</textarea>
#{/field}
</p>
<p>
#{field ‘tags‘}
<label>Enter some tags:</label>
<input type="text" size="50"
name="${field.name}" value="${post?.tags?.join(‘ ‘)}" />
#{/field}
</p>
<p>
<input type="submit" value="Publish this post to the blog" />
</p>
#{/form}
改进Admin.Save方法
public static void save(Long id, String title, String content, String tags) { Post post; if(id == null) { // Create post User author = User.find("byEmail", Security.connected()).first(); post = new Post(author, title, content); } else { // Retrieve post post = Post.findById(id); // Edit post.title = title; post.content = content; post.tags.clear(); } // Set tags list for(String tag : tags.split("\\s+")) { if(tag.trim().length() > 0) { post.tags.add(Tag.findOrCreateByName(tag)); } } // Validate validation.valid(post); if(validation.hasErrors()) { render("@form", post); } // Save post.save(); index(); }
添加Route
POST /admin/myPosts/{id} Admin.save
POST /admin/new Admin.save
。。
