They aren't instantiated directly - instead, when we create a class that\nextends <a href=\"#!/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">Ext.data.Model</a>, it will automatically create a Field instance for each field configured in a <a href=\"#!/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">Model</a>. For example, we might set up a model like this:</p>\n\n<pre><code><a href=\"#!/api/Ext-method-define\" rel=\"Ext-method-define\" class=\"docClass\">Ext.define</a>('User', {\n extend: '<a href=\"#!/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">Ext.data.Model</a>',\n fields: [\n 'name', 'email',\n {name: 'age', type: 'int'},\n {name: 'gender', type: 'string', defaultValue: 'Unknown'}\n ]\n});\n</code></pre>\n\n<p>Four fields will have been created for the User Model - name, email, age and gender. Note that we specified a couple\nof different formats here; if we only pass in the string name of the field (as with name and email), the field is set\nup with the 'auto' type. It's as if we'd done this instead:</p>\n\n<pre><code><a href=\"#!/api/Ext-method-define\" rel=\"Ext-method-define\" class=\"docClass\">Ext.define</a>('User', {\n extend: '<a href=\"#!/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">Ext.data.Model</a>',\n fields: [\n {name: 'name', type: 'auto'},\n {name: 'email', type: 'auto'},\n {name: 'age', type: 'int'},\n {name: 'gender', type: 'string', defaultValue: 'Unknown'}\n ]\n});\n</code></pre>\n\n<h1>Types and conversion</h1>\n\n<p>The <a href=\"#!/api/Ext.data.Field-cfg-type\" rel=\"Ext.data.Field-cfg-type\" class=\"docClass\">type</a> is important - it's used to automatically convert data passed to the field into the correct format.\nIn our example above, the name and email fields used the 'auto' type and will just accept anything that is passed\ninto them. The 'age' field had an 'int' type however, so if we passed 25.4 this would be rounded to 25.</p>\n\n<p>Sometimes a simple type isn't enough, or we want to perform some processing when we load a Field's data. We can do\nthis using a <a href=\"#!/api/Ext.data.Field-cfg-convert\" rel=\"Ext.data.Field-cfg-convert\" class=\"docClass\">convert</a> function. Here, we're going to create a new field based on another:</p>\n\n<pre><code><a href=\"#!/api/Ext-method-define\" rel=\"Ext-method-define\" class=\"docClass\">Ext.define</a>('User', {\n extend: '<a href=\"#!/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">Ext.data.Model</a>',\n fields: [\n {\n name: 'firstName',\n convert: function(value, record) {\n var fullName = record.get('name'),\n splits = fullName.split(\" \"),\n firstName = splits[0];\n\n return firstName;\n }\n },\n 'name', 'email',\n {name: 'age', type: 'int'},\n {name: 'gender', type: 'string', defaultValue: 'Unknown'}\n ]\n});\n</code></pre>\n\n<p>Now when we create a new User, the firstName is populated automatically based on the name:</p>\n\n<pre><code>var ed = <a href=\"#!/api/Ext-method-create\" rel=\"Ext-method-create\" class=\"docClass\">Ext.create</a>('User', {name: 'Ed Spencer'});\n\nconsole.log(ed.get('firstName')); //logs 'Ed', based on our convert function\n</code></pre>\n\n<p>Fields which are configured with a custom <code>convert</code> function are read <em>after</em> all other fields\nwhen constructing and reading records, so that if convert functions rely on other, non-converted fields\n(as in this example), they can be sure of those fields being present.</p>\n\n<p>In fact, if we log out all of the data inside ed, we'll see this:</p>\n\n<pre><code>console.log(ed.data);\n\n//outputs this:\n{\n age: 0,\n email: \"\",\n firstName: \"Ed\",\n gender: \"Unknown\",\n name: \"Ed Spencer\"\n}\n</code></pre>\n\n<p>The age field has been given a default of zero because we made it an int type. As an auto field, email has defaulted\nto an empty string. When we registered the User model we set gender's <a href=\"#!/api/Ext.data.Field-cfg-defaultValue\" rel=\"Ext.data.Field-cfg-defaultValue\" class=\"docClass\">defaultValue</a> to 'Unknown' so we see\nthat now. Let's correct that and satisfy ourselves that the types work as we expect:</p>\n\n<pre><code>ed.set('gender', 'Male');\ned.get('gender'); //returns 'Male'\n\ned.set('age', 25.4);\ned.get('age'); //returns 25 - we wanted an int, not a float, so no decimal places allowed\n</code></pre>\n</div><div class='members'><div class='members-section'><div class='definedBy'>Defined By</div><h3 class='members-title icon-cfg'>Config options</h3><div class='subsection'><div id='cfg-allowBlank' class='member first-child not-inherited'><a href='#' class='side expandable'><span> </span></a><div class='title'><div class='meta'><span class='defined-in' rel='Ext.data.Field'>Ext.data.Field</span><br/><a href='source/Field2.html#Ext-data-Field-cfg-allowBlank' target='_blank' class='view-source'>view source</a></div><a href='#!/api/Ext.data.Field-cfg-allowBlank' class='name expandable'>allowBlank</a><span> : <a href=\"#!/api/Boolean\" rel=\"Boolean\" class=\"docClass\">Boolean</a></span><strong class='private signature'>private</strong></div><div class='description'><div class='short'>Used for validating a model. ...</div><div class='long'><p>Used for validating a <a href=\"#!/api/Ext.data.Model\" rel=\"Ext.data.Model\" class=\"docClass\">model</a>.
