The goal of this extension is to simplify the usage withing Middleman of data imported from Contentul (using the [contentful_middleman](https://github.com/contentful/contentful_middleman) gem). 4 | 5 | ## Table of contents 6 | * [Installation](#installation) 7 | * [Usage](#usage) 8 | * [Extension configuration](#extension-configuration) 9 | * [Template locals](#template-locals) 10 | * [Blogging](#blogging) 11 | * [Pagination](#pagination) 12 | 13 | ## Installation 14 | 15 | Add this line to your application's Gemfile: 16 | 17 | gem 'contentful-middleman-pages' 18 | 19 | And then execute: 20 | 21 | $ bundle 22 | 23 | ## Usage 24 | 25 | ### Extension configuration 26 | 27 | 28 | ```ruby 29 | activate :contentful_pages do |extension| 30 | extension.data = 'blog.post' 31 | extension.prefix = 'blog' 32 | extension.template = 'random.html.erb' 33 | extension.permalink = 'my/nice/permalink/{title}.html' 34 | end 35 | ``` 36 | 37 | 38 | Parameter | Required | Description 39 | ----------|----------|------------ 40 | data | true | Concatenation of the space name and content type (same names used when configuring the contentful_middleman extension) that identifies the entries to be used 41 | template | true | Path to the template used to render every entry 42 | prefix | false | String that will be prepended to the value specified in `template` and `permalink` 43 | permalink | false | Uri template to specify a custom destination path for the resulting pages. Can interpolate values available in the entries 44 | 45 | #### Extension configuration: example 46 | 47 | Consider the following configuration of the contentful_middleman gem. On this case we are assigning the name partners to the space and name partner to the content type. 48 | 49 | ```ruby 50 | activate :contentful do |f| 51 | f.space = {partners: '7ujlxwexazta'} 52 | f.access_token = '437fcca0ac3ec11728782c51cc559c0dfd0d2c568b7da5345c67a1ce31de5a8f' 53 | f.cda_query = { content_type: '1EVL9Bl48Euu28QEOa44ai', include: 1 } 54 | f.content_types = { partner: {mapper: PartnerMapper, id:'1EVL9Bl48Euu28QEOa44ai'}} 55 | end 56 | ``` 57 | 58 | On the activation below we are fetching the entries stored under the key `partners.partner`. We will render each of the entries using the template `source/random.html.erb`. 59 | 60 | ```ruby 61 | activate :contentful do |extension| 62 | extension.data = 'partners.partner' 63 | extension.template = 'random.html.erb' 64 | end 65 | ``` 66 | 67 | On the activation below we are using the same entries. We have set the prefix to `partners` and so we will render each of the entries using the template `source/partners/random/html.erb`. 68 | ```ruby 69 | activate :contentful_pages do |extension| 70 | extension.data = 'partners.partner' 71 | extension.prefix = 'partners' 72 | extension.template = 'random.html.erb' 73 | end 74 | ``` 75 | 76 | 77 | On the activation below we are using the same entries. We have again set the prefix but this time we are using a custom permalink. Resulting pages will be available under `partners/my/nice/permalink/xyz.html` where `xyz` is the title of the entry used to render the page. 78 | ```ruby 79 | activate :contentful_pages do |extension| 80 | extension.data = 'partners.partner' 81 | extension.prefix = 'partners' 82 | extension.template = 'random.html.erb' 83 | extension.permalink = 'my/nice/permalink/{title}.html' 84 | end 85 | ``` 86 | 87 | ### Template locals 88 | 89 | Inside every template you will have access to the followig set of local variables: 90 | 91 | * One local variable for each one of the properties stored for every entry in the local data. 92 | * Access to all the configured resources under the variable `contentful`. 93 | 94 | #### Template locals: example 95 | 96 | Consider the following Middleman configuration: 97 | 98 | ```ruby 99 | activate :contentful do |extension| 100 | extension.data = 'partners.partner' 101 | extension.template = 'random.html.erb' 102 | end 103 | 104 | activate :contentful do |extension| 105 | extension.data = 'blog.post' 106 | extension.template = 'post.html.erb' 107 | end 108 | ``` 109 | 110 | And that: 111 | 112 | * For every entry in `data.partner` the following properties are stored: id, name, location 113 | * For every entry in `blog.post` the following properties are stored: id, slug, author_name 114 | 115 | So inside the `source/random.html.erb` template you will have access the partner properties as local variables: 116 | 117 | 118 | ```html 119 |

<%= name %>

120 | 121 | Partner location: <%= location %> 122 | ``` 123 | 124 | And inside of every template you will have access to `contentful.partners.partner` and to `contentful.blog.post`. You could write something like this: 125 | 126 | ```html 127 | 132 | 133 | 138 | ``` 139 | 140 | Please note that all the elements in `contentful.partners.partner` and `contentful.blog.post` are Middleman [resources](http://www.rubydoc.info/github/middleman/middleman/Middleman/Sitemap/Resource) and so all its methods are available to use. 141 | 142 | 143 | ### Blogging 144 | 145 | If you want to create a blog with Middleman you should use the officially supported extension [middleman-blog](https://github.com/middleman/middleman-blog). To use the `middleman-blog` extension with data imported from contentful you will have to start writing a configuration like this: 146 | 147 | ```ruby 148 | activate :blog do |blog| 149 | blog.prefix = "blog" 150 | blog.sources = "posts/:year-:month-:day-:title" 151 | end 152 | ``` 153 | 154 | The relevant part of the previous snippet is the `blog.source` configuration parameter. This parameter is used by the `middleman-blog` extension to know which resources it has to use to create the blog. To make resources created with the `contentful-middleman-pages` available to the blog extension set the permalink of each of these resources to a value that matches the `blog.sources` expression. For example: 155 | 156 | ```ruby 157 | activate :contentful_pages do |extension| 158 | extension.data = 'blog.post' 159 | extension.prefix = 'blog' 160 | extension.permalink = "posts/{year}-{month}-{day}-{slug}.html" 161 | extension.template = 'post.html.erb' 162 | end 163 | ``` 164 | 165 | ### Pagination 166 | 167 | Pagination is not built into this extension. Use [middleman-pagination](https://github.com/Aupajo/middleman-pagination) instead. 168 | -------------------------------------------------------------------------------- /LICENSE.txt: -------------------------------------------------------------------------------- 1 | 2 | Apache License 3 | Version 2.0, January 2004 4 | http://www.apache.org/licenses/ 5 | 6 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 7 | 8 | 1.
